I was in my Ubuntu home directory, trying to create a new rails app with rails new, but I got this error:
The i18n gem is not available. Please add it to your Gemfile and run bundle install
Any rails command I run gives that error. I'm really confused, because I'm not inside an application. I'm just in my home directory. There is no gemfile. I tried installing 'i18n' into my home directory with gem install 'i18n', and it worked, but I'm still getting that error.
I've never had any problems with rails commands in my home directory before. Everything rails-related works normally when I cd into my individual apps. What's going on?
Also, I'm now getting the same error in all my existing rails apps. Did rails suddenly become reliant on that gem? Or could deleting the gem in my home directory somehow have made it unavailable in my apps?
UPDATE
I tried gem cleanup rails and reinstalling, but nothing changed. Here was the result:
$ gem cleanup rails

Try gem install rails again. Or gem install rails -v 5.0 to install a specific version.
It appears you somehow don't have rails and it's dependencies fully installed. Perhaps because you reinstalled ruby or installed a different ruby version. If i'm right that's what's going on, just reinstall the latest version of rails or the version you want, and everything needed will be there again.
Are you using any version manager, rvm or rbenv? You should use this to prevent any mismatch in installing libraries and ensuring your packages are ordered.
I will suggest you to remove anything Ruby related and install Rbenv first. A quick search with that error, I found it mostly relates to RVM. I could be wrong though but try with Rbenv. Use Rbenv to setup Ruby in your Ubuntu. Here is a link for Rbenv in Ubuntu 16.04
Also, why not try to create a Gemfile and actually add gem 'i18n', '~> 0.7.0'.
Then run bundle install. If it says it is gem locked, use bundle update i18n
What does it say?
And also, what do you get with which -a ruby
You might have multiple versions of rails installed. Maybe try running gem cleanup rails
For more information on the command see gem cleanup --help
Edit: and then of course you'd have to install rails again. Either latest stable version or whichever you prefer.
UPDATE
Looking at your output of gem install it doesn't seem to install any of the dependencies, so it assumes you have i18n installed already.
Here is what you can do:
Check out which versions you have installed. Run gem list | grep i18n and grep rails respectively.
Remove all versions of these gems via gem uninstall i18n --all and gem uninstall rails --all respectively
Install rails gem install rails --version 5.0.1 and it should output Successfully installed i18n-0.9.1 during the install process.
Here's my output:

So I still don't understand exactly what was happening, but I uninstalled rails using gem uninstall rails and then reinstalled it with just gem install rails, and rails commands now work. Apparently the problem wasn't even really related to i18n. I'm at a total loss. At least it works now!
The problem is with i8ln in the the place where ruby is installed.
For example
Ruby2.3.3\lib\ruby\gems\2.3.0\gems
Try to reinstall ruby and try.
Make sure you clear all ruby files before you do a fresh install.
I was getting the same error after a messy merge on a rails 6.1.4.7 project.
I ran gem uninstall rails , switched the rails version to 7.0.4 in the Gemfile and ran bundle update. After that, all rails commands seem to be working fine.
I am installing rails 5 on aws. I have installed rvm and ruby. Ruby version I installed is 2.3.1. I have done bundle install.
Now I am trying to install rails 5 by using command - 'sudo gem install rails --version 5.0.0'
But I am getting error

Why it is showing ruby version required >= 2.2.2 ? What should I do here?
Since you are using rvm, you should install gems for the current user. That means without sudo.
gem install rails --version 5.0.0
I'm trying to incorporate travis ci in my project, the travis console output shows
An error occurred while installing momentjs-rails (2.11.0), and Bundler cannot
continue.
Make sure that `gem install momentjs-rails -v '2.11.0'` succeeds before
bundling.
even though in my .travis.yml I have
language: ruby
rvm:
- 2.2.1
before_install:
- gem update --system
- gem --version
- gem install momentjs-rails -v '2.11.0'
when I check the before install for moment js, it does say that

so why is my build still getting the error with this gem?
I downloaded the MSCollectionViewCalendarLayout and now I wanted to try out the example. If I open the Example.xcodeproj I only get errors e.g.
Lexical or Preprocessor Issue 'RestKit/RestKit.h' file not found
I tried the tip from the troubleshooting guide to change the project settings but it didn't worked. If I open the Example.xcworkspace I also only get errors.
Seems that the libraries are outdated. Is there a chance to get this project running?
Edit:
Now I tried to install cocoapods. I created a .profile file in my home directory (where Documents, Desktop, Downloads resides in). I put this text into the file
export GEM_HOME=$HOME/.gem
export PATH=$GEM_HOME/bin:$PATH
and then I run
gem install cocoapods --user-install

Then I reopened the Xcode example, but I'm still getting the error that RestKit.h can't be found. What I'm doing wrong?
Edit 2:
Now I tried to use pod install in the example directory, but the pod command was not found. So I edited the PATH in .profile to this
export PATH=$GEM_HOME/ruby/2.0.0/bin:$PATH
Then I restarted terminal and run the command again

Afterwards I opened Example.xcworkspace and got the error described by Jakub Vano. Then I unlocked and edited the MASUtilities.h according to this link (commented enum and added the static const).
Now I got the project running!
You need to re-install CocoaPods for Example project:
run pod install in the Example project directory
run the project from the .xcworkspace
There will still be compile errors caused by known issue with Masonry - as mentioned on linked issue, workaround is to replace problematic enum with
typedef float MASLayoutPriority;
static const MASLayoutPriority MASLayoutPriorityRequired = UILayoutPriorityRequired;
static const MASLayoutPriority MASLayoutPriorityDefaultHigh = UILayoutPriorityDefaultHigh;
static const MASLayoutPriority MASLayoutPriorityDefaultMedium = 500;
static const MASLayoutPriority MASLayoutPriorityDefaultLow = UILayoutPriorityDefaultLow;
static const MASLayoutPriority MASLayoutPriorityFittingSizeLevel = UILayoutPriorityFittingSizeLevel;
I have a very old rails app (rails 2.3.10 and ruby 1.8.7) and we want to move it on another server.
I can reinstall all gems with same version except for paperclip 2.7.
when i tried to install it i receive an error on activesupport, that it seems it require ruby 1.9.3. According with paperclip doc this shouldn't happens, some one of you can help me?
i tried with all gems except paperclip, with no gems, and installing an old version of activesupport. Below you can find my tests.

You will have to build the gem manually and use the file from the pull request here: https://github.com/thoughtbot/paperclip/pull/1270. - Ralph
