Firebase pods not downloading - ios

I have looked at multiple sites (including GitHub), but no matter what I do, It doesn't seem to work. I have tried uninstalling and reinstalling cocoapods, I even did this:
gem list --local | grep cocoapods
sudo gem uninstall cocoapods
sudo rm -rf ~/.cocoapods
sudo gem install cocoapods
cd (PROJECT DIRECTORY)
pod init
(put cocoapod in podfile)
pod install
But it still doesn't work.
The specific error is RuntimeError - [Xcodeproj] Unknown object version.
After that,
It starts listing Ruby libraries. Before It was working, but now it isn't. The pod I added was Firebase/Database.
Any help would be greatly appreciated!

I figured it out by first checking my xcodeproj version using
gem list
Then, if your version is less than or equal to 15, update it using
sudo gem update xcodeproj

Cocoapods behaving awkwardly [duplicate]

I'm having some issues installing Alamofire 4.0 into my project.
I've got the latest version of Xcode, running Swift 3, and when I try to install alamofire I'm getting like 800 compiler errors.
Apparently
CocoaPods 1.1.0+ is required to build Alamofire 4.0.0+
[!] some_cocoapod requires CocoaPods version >= X.Y.Z, which is not satisfied by your current version, Z.Y.X.
I looked at the version of CocoaPods I have in terminal and it says I'm at 1.0.1.
Running an update didn't work I guess because CocoaPods 1.1 is in beta.
So I'm not exactly sure how to update it up to where I'm good to go.
Unless being out of date doesn't force like 800 compiler errors? Does that sound like some other issue?
Execute the following on your terminal to get the latest stable version:
sudo gem install cocoapods
Add --pre to get the latest pre release:
sudo gem install cocoapods --pre
If you originally installed the cocoapods gem using sudo, you should use that command again.
Later on, when you're actively using CocoaPods by installing pods, you will be notified when new versions become available with a CocoaPods X.X.X is now available, please update message.
Open the Terminal -> copy below command
sudo gem install cocoapods
It will install the latest stable version of cocoapods.
after that, you need to update pod using below command
pod setup
You can check pod version using below command
pod --version
If you got System Integrity Protection enabled or any other permission write error, which is enabled by default since macOS Sierra release, you should update CocoaPods, running this line in terminal:
sudo gem install cocoapods -n/usr/local/bin
After installing, check your pod version:
pod --version
You will get rid of this error:
ERROR: While executing gem ... (Gem::FilePermissionError)
You don't have write permissions for the /usr/bin directory
And it will install latest CocoaPods:
Successfully installed cocoapods-x.x.x
Parsing documentation for cocoapods-x.x.x
Installing ri documentation for cocoapods-x.x.x
Done installing documentation for cocoapods after 4 seconds
1 gem installed
If you are using Homebrew, open terminal and type:
brew upgrade cocoapods
If that does not work, try:
brew install cocoapods
After that, run:
brew link --overwrite cocoapods
For those with a sudo-less CocoaPods installation (i.e., you do not want to grant RubyGems admin privileges), you don't need the sudo command to update your CocoaPods installation at all:
gem install cocoapods
You can find out where the CocoaPods gem is installed with:
gem which cocoapods
If this is within your home directory, you should definitely run gem install cocoapods without using sudo.
Finally, to check which CocoaPods you are currently running type:
pod --version
I had to do this, was stuck on 1.9.1 on macOS
sudo gem install -n /usr/local/bin cocoapods
Below are steps to update cocoapods :
Open terminal (Shortcut : Press cmd + space tab to open Spotlight then text in terminal)
Use command sudo gem install cocoapods. This will ask for system password due to security concern thereafter it installs gems
Now, set up pod using pod setup command. This will setup cocoapods master repo.
You can check the version of cocoapods using pod --version command.
Non of the above solved my problem, you can check pod version using two commands:
pod --version
gem which cocoapods
In my case pod --version always showed "1.5.0" while gem which cocopods shows
Library/Ruby/Gems/2.3.0/gems/cocoapods-1.9.0/lib/cocoapods.rb. I tried every thing but unable to update version showed from pod --version. sudo gem install cocopods result in installing latest version but pod --version always showing previous version. Finally I tried these commands:
sudo gem update
sudo gem uninstall cocoapods
sudo gem install cocoapods
pod setup``pod install
The catch for me was sudo gem update. Hopefully it will help any body else.
You can solve this problem by these Commands:
First:
sudo gem install cocoapods
Desp: type user mac password now your cocoapods will be replace with a stable version.
You can find out where the CocoaPods gem is installed with:
gem which cocoapods
if you have cloned the repo then type this command:
pod repo update
close your xcode and run this command
Pod install
This is a really quick & detailed solution
Open the Terminal and execute the following to get the latest stable version:
sudo gem install cocoapods
Add --pre to get the latest pre release:
sudo gem install cocoapods --pre
Incase any error occured
Try uninstall and install again:
sudo gem uninstall cocoapods
sudo gem install cocoapods
Run after updating CocoaPods
sudo gem clean cocoapods
After updating CocoaPods, also need to update Podfile.lock file in your project.
Go to your project directory
pod install
Very Smoot and Easy Solution
//MARK: -Latest stable version:
sudo gem install cocoapods --pre
//MARK: -If not work then
sudo gem install cocoapods --pre -n /usr/local/bin
//MARK: - if upper command not works you can use below mention command as well!
brew install cocoapods
brew upgrade cocoapods
brew link cocoapods
If this
sudo gem install cocoapods
gives you this error:
Could not find a valid gem 'cocoapods' (>= 0) in any repository
Try this:
sudo gem install cocoapods --source http://rubygems.org
I tried updating and it didn't work. Finally , I had to completely remove (manually )cocoapods, cocoapods-core , cocoapods-try.. and any other package used by cocoapods. Use this terminal command to list all the packages:
gem list --local | grep cocoapods
After that , I also deleted ./cocoapods folder from the user's root folder.
After trying all the steps above, with nothing working, I ran bundle update which seems to have done the trick for me.
Refer this link https://guides.cocoapods.org/using/getting-started.html
brew install cocoapods
brew upgrade cocoapods
brew link cocoapods
I have the problem in myproject when pod version and gem which cocoapods always return difference version.
All I had to do is remove Gemfile.lock in my project and bundle install again. It removed the locked cocoapods version and install a newer one.
Hope that helps some one here.
On my M1 Mac, I had a separate version of Homebrew installed for the Silicon/Arm64 side.
brew upgrade cocoapods was defaulting to a rosetta install of homebrew. I kept running it, and couldn't figure out why cocoapods was not updating. So I had to run it in a way that targets the M1 side of things instead of Rosetta.
I had previously aliased the Arm brew to mbrew. So I had to run mbrew upgrade cocoapods
If you updated sudo gem install cocoapods but it's still showing the old version you just need to type bundle update in your terminal to update the bundle and pod --version will show the newest version you installed
write on your terminal this:
sudo gem install cocoapods --pre
for update the gem of cocoapods to lastest version
First check cocoapods versionlike
pod --version
then update like
sudo gem install cocoapods --pre
after update you can also check cocoapods version.
I change the line "pod 'Alamofire', '~> 4.0'" to "pod 'Alamofire', :git => 'https://github.com/Alamofire/Alamofire', :commit => '3cc5b4e'" after that in terminal: "pod install --repo-update" and it works.

Where is the pod file in xcode located? [duplicate]

I referred to many links and tried, but I had no success. I read CocoaPods documents and many times tried to install, but I always failed because of the starting steps. I found one error whereby I can't install gems first. What are the steps one by one? Such as steps or a demo of how to install.
This is one link which I tried.
The screenshot refers to this console error I was given:
POD Install
Open terminal and type:
sudo gem install cocoapods
The Gem will get installed in Ruby inside the System library. Or try on Mac OS X v10.11 (El Capitan), type:
sudo gem install -n /usr/local/bin cocoapods
If there is an error "activesupport requires Ruby version >= 2.xx", then install latest activesupport first by typing in the terminal.
sudo gem install activesupport -v 4.2.6
After installation, there will be a lot of messages. Read them and if no error found, it means the CocoaPods installation is done. Next, you need to setup the CocoaPods master repository. Type in the terminal:
pod setup
And wait it will download the master repository. The size is very big (370.0 MB in December 2016). So it can be a while. You can track of the download by opening Activity and go to the Network tab and search for "git-remote-https". Alternatively, you can try adding "--verbose" to the command like so:
pod setup --verbose
Once done, it will output "Setup Complete", and you can create your Xcode project and save it.
Then in the terminal, cd to your Xcode project root directory (where your .xcodeproj file resides) and type:
pod init
Then open your project's podfile by typing in terminal:
open -a Xcode Podfile
Your Podfile will get open in text mode. Initially there will be some default commands in there. Here is where you add your project's dependencies. For example, in the podfile, type
pod 'AFNetworking', '0.9.1'
(This line is an example of adding the AFNetworking library to your project.)
Other tips:
Uncomment platform :ios, '9.0'
Uncomment use_frameworks! if you're using Swift
When you are done editing the podfile, save it and close Xcode.
Then install pods into your project by typing in terminal:
pod install
or (For m1 chip)
arch -x86_64 pod install
Depending how many libraries you added to your podfile for your project, the time to complete this varies. Once completed, there will be a message that says
"Pod installation complete! There are X dependencies from the Podfile
and X total pods installed."
Now close your Xcode project. Then locate and open the .xcworkspace Xcode project file and start coding. (You should no longer open the xcodeproj file.)
First open your terminal
Then update your gem file with command
sudo gem install -n /usr/local/bin cocoapods
Then give your project path
cd /your project path
Touch the podifle
touch podfile
Open your podfile
open -e podfile
It will open a podfile like a text edit. Then set your target. For example if you want to set up Google maps then your podfile should be like
use_frameworks!
target 'yourProjectName' do
pod 'GoogleMaps'
end
Then install the pod
pod install
On macOS v10.14 (Mojave) with Xcode 10.3, I got scary warnings from the gem route with or without -n /usr/local/bin:
xcodeproj's executable "xcodeproj" conflicts with /usr/local/bin/xcodeproj
Overwrite the executable? [yN]
What works for me is still Homebrew. Just:
brew install cocoapods
This works for Mac OS X v10.11.x (El Capitan)
sudo gem install -n /usr/local/bin cocoapods
After this, you can set up the pod using pod setup cmd and then move to your project directory and install pod.
Simple steps to install a pod file:
Open the terminal
Command on the terminal: sudo gem install cocoapods
Set your project path in the terminal.
Command: pod init
Go to the pod file of your project and add the pod which you want to install
Added in the pod file: pod 'AFNetworking', '~> 3.0
Command: Pod install
Close the Xcode project
open your project from the terminal
Command: open PodDemos.xcworkspace
Year 2020, installing CocoaPods v1.9.1 in macOS v10.15 (Catalina)
First set up your Xcode version in your Mac using the terminal.
sudo xcode-select -switch /Applications/Xcode.app
Next, install CocoaPods using the terminal.
sudo gem install cocoapods
For more information, visit the official website, https://cocoapods.org/.
These are the complete steps that I usually follow. I am posting these steps as short as possible and assuming that you know about Mac and Xcode projects. First of all, open the terminal and use the following commands, and press enter after each command.
Type in the following command if you don't already have CocoaPods installed:
sudo gem install cocoapods
Now please move to your Xcode Project directory by using this following command, and replace /Your Xcode Project Directory Path with the actual path to the directory:
cd /Your Xcode Project Directory Path
Below are instructions for how to use CocoaPods. Please wait for some time after each and every command entered to the terminal to execute successfully.
Searching for pods in terminal:
pod search networking (replace networking with which you want to search)
Creating the pod file:
pod init
Opening the pod file:
open -a Xcode Podfile
Adding the pods: (After adding your pods you must save the podfile first and then head back to the terminal again.)
target 'WebServiceUsingMantleAFNetworking' do
# platform :ios, '8.0' //Choose your version of iOS
pod 'AFNetworking', '~> 2.6.0’
end
OR
platform :ios, '8.0'
pod 'AFNetworking'
pod 'Mantle'
pod 'LBBlurredImage'
pod 'TSMessages'
pod 'ReactiveCocoa'
Installing the pods:
pod install
Check for updates of pods on existing project:
pod outdated
Update the existing pods:
pod update
Uninstall the Cocoapods from system:
sudo gem uninstall cocoapods
There is a complete tutorial for removing pods from your Xcode project on Stack Overflow. You can check on this following link for more info.
How to remove CocoaPods from a project?
Open Terminal
Type in sudo gem install cocoapods if you don't have CocoaPods
Enter cd /project path, but replace project path with actual project path
touch podfile
Use one of the following commands to open the podfile:
open -e podfile to open in TextEdit or
open -a pod file to open in Xcode
Set your target and add pod file of GoogleMaps like as:
target 'PROJECT NAME HERE' do
pod 'GoogleMaps'
end
Use pod install to install dependencies
Here are all steps with an image. Please follow it properly and I am sure you will not get any error.
From How to install CocoaPods and setup with your Xcode project.
First of all, check you have to install command line or not.
You can check this by opening Xcode, navigating the menu to
Xcode → Preferences → Downloads → Components. Find Command Line Tools and select install/update.
If you haven't found command line tool then you need to write this command in the terminal:
xcode-select --install
And click on install.
If you have installed the command-line tool, you need to select your Xcode directory (sometimes these type of problems created due to different versions of Xcode available)
Follow this procedure.
Open terminal and run this command:
sudo gem install cocoapods
Enter the admin password. This could take a while. After a few minutes, it
will show a green message if CocoaPods installed successfully in your
Mac machine.
If you are getting any error with Xcode 6 like developer path is
missing. First run this command in terminal:
sudo xcode-select -switch /Applications/Xcode6.app (or your XCodeName.app)
Now you can set up Pod with your Xcode project.
And now you have to install pod. Follow this procedure.
Open Terminal
Change directory to your Xcode project root directory (where your
ProjectName.xcodeproj file is placed).
pod setup: (Setting up the CocoaPods master repository)
If successful, it shows: Setup completed (read-only access). So,
you set up everything. Now let’s do something which is more visible…Yes! Let’s install libraries in your Xcode project.
Now you have to set up and update the library related to pod in your project.
Steps to add-remove-update libraries in pod:
Open Terminal
Change directory to your Xcode project root directory. If your
terminal is already running then there isn't any need to do this, as you are
already at the same path.
touch pod file
open -e podfile (This should open a blank text file)
Add your library names in that text file. You can add new names
(library name), remove any name or change the version, e.g.:
pod ’Facebook-iOS-SDK’
pod ’EGOTableViewPullRefresh’
pod ’JSONKit’
pod ‘MBProgressHUD
NOTE: Use the (control + ”) button to add single quote at both end of library name. It should be shown as straight vertical line. Without
control button it shall be added as curly single quote which will give
error while installation of file.
Save and close this text file. Now libraries are set up and you have
to install/update it
Go to your terminal again and run this command: pod install
(to install/update these libraries in pod).
You should see output similar to the following:
Updating spec repo `master’ \
Installing Facebook-iOS-SDK \
Generating support files
Setup completed.
Note:
If you have followed this whole procedure correctly and step by step, then you can directly fire the pod update command after selecting Xcode and then select your project path. And write your command pod update.
You can also check a command line tool here:
CocoaPods Installation on macOS v10.13 (High Sierra):
Install Homebrew - https://brew.sh/
Execute the following commands in the terminal:
sudo gem update --system
sudo gem install activesupport -v 4.2.6
sudo gem install -n /usr/local/bin cocoapods
pod setup
pod setup --verbose
For macOS v10.15 (Catalina):
sudo gem install -n /usr/local/bin cocoapods -v 1.8.4
The latest CocoaPods 1.10.0 seem not to be working.
I found the answer in Trouble with installing CocoaPods.
1- Install the Cocoapods in your machine
$ sudo gem install cocoapods
$ pod setup --verbose
2- Check whether Cocoapods is installed on your machine or not?
$ pod --version
3- Go to your project directory where .xcodeproj is present
$ pod init
After using pod init one additional file is added in your folder of name Podfile.
4- By double click open the podfile and pods between target and end
5- Install Pod using command
pod install
When you run the pod install command it installs all pods which you write in the pod file. And after you install the required commands open the project directory you get 2 new files.
First is Podfile.lock -> Every time the pod install command is run — and downloads and install new pods — it writes the version it has installed, for each pod, in the Podfile.lock file.
Second is .xcworkspace -> Xcode workspace files can be used as a wrapper or container for an Xcode .XCODEPROJ project.
Now use your library by using .xcworkspace which have a white background colour.
Pod installation giving an error on Mac OS X v10.11.2 (El Capitan):
ERROR: Error installing cocoapods:
activesupport requires Ruby version >= 2.2.2.
After getting this error, I tried this command and installed again. It worked for me.
sudo gem install activesupport -v 4.2.6
Now try the same pod installation command
sudo gem install -n /usr/local/bin cocoapods
For me, the easiest way was to install via a Ruby gem:
sudo gem install cocoapods -v
Please note -v for verbose. It takes a while to install CocoaPods and often you get confused if it's really happening.
You can install CocoaPods via Homebrew in macOS.
First, open your terminal, and run this code (for installing Homebrew if you have not): Go here for the latest command.
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
Then install CocoaPods easily via this command:
brew install cocoapods
sudo gem install -n /usr/local/bin cocoapods
This worked for me. -n helps you fix the permission error.
Pod File Install Steps
sudo gem install -n /usr/local/bin cocoapods
Pod setup
cd ~/Path/To/Folder/Containing/ShowTracker
touch podfile
open -a Xcode Podfile // To open it in Xcode
OPEN -e podfile // To open it in text editor
pod install // To install a new pod
pod update // To update all pods
Works in macOS Big Sur
1 install LATEST version of brew (https://treehouse.github.io/installation-guides/mac/homebrew)
2 then use "brew uninstall cocoapods"
3 install the latest version of cocoapods using "brew install cocoapods" (You must verify installed version with github version https://github.com/CocoaPods/CocoaPods/releases/tag/1.11.2, they must match)
4 overwrite link to cocoapods with "brew link --overwrite cocoapods"
5 check the version of cocoapods "pod --version"
6 done, You have the latest version of cocoapods installed
Normally we use
sudo gem install cocoapods
Solution, fix for CocoaPods error on Mac OS X v10.11 (El Capitan):
sudo gem install -n /usr/local/bin cocoapods
pod setup
cd /project path
pod init
In Podfile we need to set the target
# Podfile
platform :ios, '9.0'
use_frameworks!
# My other pods
target “Projectname” do
pod 'MBProgressHUD', '~> 0.8'
pod 'Reachability', '~> 3.1.1'
pod 'AFNetworking', '~> 2.2'
pod 'TPKeyboardAvoiding', '~> 1.2'
end
target 'ProjectnameTests' do
testing_pods
end
target 'ProjectnameUITests' do
testing_pods
end
In the console - terminal
pod install
If you behind a proxy then pass the proxy as an argument:
sudo gem install --http-proxy http://user:password#www-proxy.example.com:80 cocoapods
Thanks to SwiftBoy's 10-step solution I successfully used CocoaPods to setup the latest version of AudioKit.
1. Using Xcode create MyAudioApp Swift project saving it to my Developer directory e.g.
/Users/me/Developer/MyAudioApp
2. Using Cocoapods install AudioKit within MyAudioApp project (i.e. install AudioKit sdk)
3. Open Terminal, type command below and press Enter
sudo gem install -n /usr/local/bin cocoapods
4. Provide system password and press Enter
5. In Terminal, type command below and press Enter
cd /Users/me/Developer/MyAudioApp
6. Create project pod file - in Terminal type command below and press Enter
touch Podfile
7. Open project pod file - in Terminal type command below and press Enter (opens in TextEdit)
open Podfile
8. Edit code below into open pod file (and save file before quitting TextEdit)
source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '12.2'
use_frameworks!
target 'MyAudioApp' do
pod 'AudioKit', '~> 4.7'
end
9. To install AudioKit in MyAudioApp workspace type Terminal command below and press Enter
Pod install
and wait for install to finish
10. In Finder, go to project folder /Users/me/Developer/MyAudioApp
and click .xcworkspace file below (opens in Xcode!)
/Users/me/Developer/MyAudioApp/MyAudioApp.xcworkspace
11. In MyAudioApp edit ViewController.swift and insert the following
import AudioKit
CocoaPods installation step:
Open your Terminal:
sudo gem update --system
sudo gem install activesupport -v 4.2.6
sudo gem install cocoapods
pod setup
pod setup --verbose
Then go to your project directory with Terminal:
cd Your Project Path
Then enter the below command in Terminal:
pod init
open -a Xcode Podfile
(Edit POD file with pod ‘libname’)
pod install
For CocoaPods in the terminal, follow this:
sudo gem update
sudo gem install cocoapods
pod setup
cd (project direct drag link)
pod init
open -aXcode podfile # (If it’s already open, add your pod file name. Example: alamofire4.3)
pod install
pod update
Open Terminal
Enter $ sudo gem install cocoapods command in terminal
Create new Xcode project
Navigate to directory containing Xcode project. Use cd “../directory-location/..” or cd [drag-and-drop project folder]
Pod install
If this prompts error Unable to add a source with url.. then install command line tool for Xcode. Again, rerun Pod install command.
This will install all dependencies as well.
Now, open your project in Workspace i.e. Project-Name.xcworkspace rather than Project-Name.xcodeproj
If you want to install CocoaPods for the first time for your project.
Example: Here we will install the "Alamofire" SDK using CocoaPods step by step.
Step 1. Open Terminal, hit command, and then press the Enter key
sudo gem install cocoapods
Step 2. If it asks, you should provide system password and then press the Enter key
Step 3. With command “cd” and give the path of your project and then press the Enter key
Note: type the "cd" command then space and drag the project folder to the terminal. It will take the project path as shown below (here my project name is: Simple Alamofire)
cd /Users/ramdhanchoudhary/Documents/Swift\ Workspace/Simple\
Alamofire
Step 4. Create a pod file in your project by terminal by command “touch Podfile” and press “Enter”
touch Podfile
Step 5. Then, open “Podfile” by terminal command “open Podfile” and press “Enter”
open Podfile
Step 6. Now type following code in opened pod file then save and close file
source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '10.0'
use_frameworks!
target '<Your Target Name>' do
pod 'Alamofire', '~> 4.0'
end
Step 7. Back in Terminal type command “Pod install” and then press Enter Key.
Pod install
Step 8. Wait for the install to get complete 100% its around 650+ MB
Step 9. That's it goto project folder and open below file
<your project name>.xcworkspace
Step 10. Import Alamofire class and use!!
import Alamofire

I had two cocoapods installed, one was using brew and one with gem. With 2 different versions.
After reading many of your posts, and try many things I encountered various troubles.
Finally this one help me : thanks to Evan
With his post : https://stackoverflow.com/a/70600723/2355088
The final working sequence for me probably was :
sudo gem uninstall cocoapods
brew uninstall cocoapods
brew install cocoapods
brew reinstall ruby

For Mac OS X v10.11 (El Capitan)
rvm install ruby-2.2.2.
rvm use ruby-2.2.2.
sudo gem install -n /usr/local/bin cocoapods
I was facing the same problem in mac after updating to macOS 12.1
Also you might get error attached with Ruby framework installed on your mac machine.
You just need to remove cocoa pods completely from mac and re-install cocoapods
And then reinstall your project pods
This will solve your problem

$ sudo gem uninstall ffi && sudo gem install ffi -- --enable-libffi-alloc

How to use a specific version of CocoaPods

Is it possible to somehow specific the version of CocoaPods I'd like to use when upgrading or installing a Podfile? I've encountered several times where Podfiles work correctly with one version of CocoaPods but not with others.
For example, the syntax I'm looking for is like the following:
pod -v 0.34 install
Since CocoaPods is installed through RubyGems you can use their mechanisms for doing this. As outlined here you can do this:
pod _0.34.0_ install
You can verify this is working with:
pod _0.34.0_ --version
Also I would highly advise against doing this at all. I would definitely recommend you keep CocoaPods up to date and change your Podfile as needed to adapt to new versions. At anytime your old version could stop working as expected if we bump the minimum version number.
the ultimate solution:
run a bash script to completely uninstall your current verison (Optinal)
for i in $( gem list --local --no-version | grep cocoapods ); do
sudo gem uninstall $i;
done
sudo gem uninstall xcodeproj
install a specific verison of CocoaPod
gem install cocoapods -v 0.39.0

Error installing CocoaPods

I am trying to install the latest CocoaPods (which is 0.36.1) but it shows me the following error.
$ gem install cocoapods
ERROR: Could not find a valid gem 'xcodeproj' (~> 0.23.1) in any repository
Sudo?
Btw, in the answered questions some are proposed using sudo get install cocoapods. You do need sudo indeed if you are using the system-wide ruby executable. I am using rbenv for my ruby management, it is installed locally for the user and does not need sudo.
Update
The gem install cocoapods command worked the following day. Mystery.
I think you could try an older version of the pods.
I tried: sudo gem install cocoapods -v 0.34.0 and this worked for me.
For your error you should do like this
i) $ sudo gem install xcodeproj
ii) $ sudo gem install cocoapods
for pod version you can verify pod --version
I think you need to update your gems repo.
try issuing "gem update" in a terminal. Can't remenber if you need sudo.
Try that, and then try installing xcodeproj and cocoapods again.
Regards
Steffen
If the automatic downloading of xcodeproj 0.23 fails, you can fetch the gem file manually:
gem fetch xcodeproj -v 0.23.0
This will put the .gem file in your current directory.
Then you can install the gem:
gem install xcodeproj -v 0.23.0
If the xcodeproj gem installs successfully, you can continue with your install of cocoapods as usual:
gem install cocoapods
Next time that occurs, run the command gem sources -u to update your source cache and try again.

Remove or uninstall library previously added : cocoapods

I added an external framework via cocoapods into my iOS application. How can i remove that library from the project?
Remove lib from Podfile, then pod install again.
The unwanted side effects of simple folder delete or installing over existing installation have been removed by a script written by Kyle Fuller - deintegrate and here is the proper workflow:
Install clean:
sudo gem install cocoapods-clean
Run deintegrate in the folder of the project:
pod deintegrate
Clean (this tool is no longer available):
pod clean
Modify your podfile (delete the lines with the pods you don't want to use anymore) and run:
pod install
Done.
Remove the library from your Podfile
Run pod install on the terminal
None of these worked for me. I have pod version 1.5.3 and the correct method was to remove the pods that were not longer needed from the Podfile and then run:
pod update
This updates your Podfile.lock file from your Podfile, removes libraries that have been removed and updates all of your libraries.
To completely remove Pod or Cocoapods Framework from your Project repository !
sudo gem install cocoapods-clean
pod deintegrate
pod clean
Then Try to remove the File
Pods
Podfile
Podfile.lock
yourProjectName.xcworkspace
Remove pod name(which to remove) from Podfile and then
Open Terminal, set project folder path
Run pod install --no-integrate
Remove pod name from Podfile then
Open Terminal, set project folder path and
Run pod update command.
NOTE: pod update will update all the libraries to the latest version and will also remove those libraries whose name have been removed from podfile.
First, determine which versions of Cocoapods are installed :
gem list --local | grep cocoapods
You get output as this:
cocoapods (1.11.2)
cocoapods-clean (0.0.1)
cocoapods-core (1.11.2, 1.10.2, 1.10.1)
cocoapods-deintegrate (1.0.4)
To completely remove, issue the following commands:
gem uninstall cocoapods
gem uninstall cocoapods-clean
gem uninstall cocoapods-core
gem uninstall cocoapods-deintegrate
Running again to confirm that Cocoapods has been removed:
gem list --local | grep cocoapods
You may have residual artefacts in a hidden folder in your directory. Remove these with:
rm -rf ~/.cocoapods
