Ruby 'gem install' won't work - ruby-on-rails

I am behind a firewall with internet blocker installed. I have power user previlage so I was able to install from git etc. But I am facing this only when I try installing 'gem'. Here is what I get, I think it says it recieved some error instead of a gzip.
Is there any config that I need to change? or any port or anything?? does it use ftp???
Please help..
[root#max-desktop max # gem install mongrel
ERROR: While executing gem ... (Zlib::GzipFile::Error)
not in gzip format

Check out the Rubygems page for Mongrel, where there is a download link.
$ wget http://rubygems.org/downloads/mongrel-1.1.5.gem
$ sudo gem install mongrel-1.1.5.gem
As a reminder, Mongrel has runtime dependencies that need to be installed first (you can use these same steps).

no idea, but maybe try upgrading rubygems?
sudo gem update --system

Error with Bundle Install (Linux)

Upon trying to start a new Rails App on Linux, I am receiving this error:
I am a newbie to this software. Please help!
Thanks :)
My Error
UPDATE: I ran 'sudo gem install bundler', and it worked but now received this error!
'/usr/bin/ruby2.3: No such file or directory -- /usr/bin/bundle (LoadError)'
My new error
It seems like you dont have bundler gem installed.
Try:
gem install bundler
Bundler is missing.
Try the below commands.
[sudo] gem install bundler
bundle install
Try stop using sudo in your commands. According to your new capture, you are using sudo with gem install bundler, and maybe that is conflicting with your configuration.
Take this link for reference for sudo usage with gem

Gem install encoding error after enironment changed from Win to Linux

I am trying to install pgsql gem, but I have some strange encoding issue when trying to install. Whole app have just been migrated from windows environment to Linux environment, but only default gemfile was used. I have found that way to solve is to change locale in registry.rb, but as I mentioned, my environment is Linux. Gist of gem_make.out can be viewed here: gist
postgresql is installed and runing:
$ service postgresql status
9.3/main (port 5432): online
EDIT: Seems that this issue is only happening with pgsql gem, other gems are installing sucessfuly, for example, running $ gem install A_123 installs specified gem successfully.
According to similar question on SO, to which SO user grenierm5 pointed me,i t seems that installing ruby-dev headers for compiling extension modules did the trick.
sudo apt-get install ruby-dev && sudo gem install pg

Gem error to install

I try to install rails but I am faced to the following error.
Has somebody any idea how to resolve it ?
C:\Users\Utilisateur>gem -v

C:\Users\Utilisateur>gem install rails
ERROR: Could not find a valid gem 'rails' (>= 0), here is why:

First try to update ruby gems.
gem update --system
The issue most likely is with your internet connection.
If you see this issue again, try
gem install rails --source http://rubygems.org
You can add the not https source permanently like this
gem sources -a http://rubygems.org
Do you want to add this insecure source? [yn]y
I want to give you one more tip:
Don't develop rails on windows. Ruby and rails and many gems are very UNIXy in their ways. Install virtualbox and ubuntu on a virtual machine and run you development for there.
You might have proxy in your system. So use sudo http_proxy=http://host:port gem install rails.
I had the same issue but I ran the "Start command prompt with Ruby" as an administrator and tried the gem install rails and it worked.
I had to run 'gem install' as root to get this to work. I.e. 'sudo', which is less than ideal.
I suspect 'gem' has very poor error reporting and doesn't communicate the real cause from a permissions issue deep down the stack.
In my country for some strange reason rubygems.org domain is blocked. So a vpn was the solution for me.
My problem was I had configured a proxy in my network connection as #theBuzzyCoder said, so I simply changed my connection and it worked, I could install my gem (sass in my case)

bundle install fails with SSL certificate verification error

When I run bundle install for my Rails 3 project on Centos 5.5 it fails with an error:
Gem::RemoteFetcher::FetchError: SSL_connect returned=1 errno=0 state=SSLv3
read server certificate B: certificate verify failed
(https://bb-m.rubygems.org/gems/multi_json-1.3.2.gem)
An error occured while installing multi_json (1.3.2), and Bundler cannot continue.
Make sure that `gem install multi_json -v '1.3.2'` succeeds before bundling.
When I try to install the gem manually (by gem install multi_json -v '1.3.2') it works. The same problem occurs with several other gems. I use RVM (1.12.3), ruby 1.9.2, bundler 1.1.3.
How to fix it?
Update
Now that I've karma wh..err mined enough from this answer everyone should know that this should have been fixed.
re: via Ownatik again bundle install fails with SSL certificate verification error
gem update --system
My answer is still correct and left below for reference if that ends up not working for you.
Honestly the best temporary solution is to
[...] use the non-ssl version of rubygems in your gemfile as a temporary workaround.
via user Ownatik
what they mean is at the top of the Gemfile in your rails application directory change
source 'https://rubygems.org'
to
source 'http://rubygems.org'
note that the second version is http instead of https
Replace the ssl gem source with non-ssl as a temp solution:
gem sources -r https://rubygems.org/
gem sources -a http://rubygems.org/
The reason is old rubygems. You need to update system part using non ssl source first:
gem update --system --source http://rubygems.org/ (temporarily updating system part using non-ssl connection).
Now you're ready to use gem update.
If you're on a mac and use a recent version of RVM (~1.20), the following command worked for me.
rvm osx-ssl-certs update
This issue should now be fixed. Update rubygems (gem update --system), make sure openssl is at the latest version on your OS, or try these tips of it's still not working: http://railsapps.github.com/openssl-certificate-verify-failed.html
Temporary solution (as alluded to by Ownatik):
Create or modify a file called .gemrc in your home path, including the line :ssl_verify_mode: 0
This will prevent bundler from checking the SSL certificates of gems when it attempts to install them.
For *nix devices, 'home path' means ~/.gemrc. You can also create /etc/gemrc if you prefer. For Windows XP, 'home path' means c:\Documents and Settings\All Users\Application Data\gemrc. For Windows 7, C:\ProgramData\gemrc
On windows7 you can download the cacert.pem file from here and set the environementvariable SSL_CERT_FILE to the path where you store the certificate eg
SET SSL_CERT_FILE="C:\users\<username>\cacert.pem"
or you can set the variable in your script like this ENV['SSL_CERT_FILE']="C:/users/<username>/cacert.pem"
Replace <username> with you own username.
The real solution to this problem, if you are using RVM:
Update rubygems: gem update --system
Use RVM to refresh SSL certs: rvm osx-ssl-certs update all
Hat tip to this tip on the RailsApps project!
You can download a list of CA certificates from curl's website at http://curl.haxx.se/ca/cacert.pem
Then set the SSL_CERT_FILE environment variable to tell Ruby to use it. For example, in Linux:
$ SSL_CERT_FILE=~/cacert.pem bundle install
(Reference: https://gist.github.com/fnichol/867550)
For those of you that have ruby installed through RVM and want a quick fix (preferring not to read per Bruno's request) just try this:
rvm remove 1.9.x (or whatever version of ruby you are using)
rvm pkg install openssl
rvm install 1.9.2 --with-openssl-dir=$rvm_path/usr
For a more details, here is the link where I found the solution.
http://railsapps.github.com/openssl-certificate-verify-failed.html
BTW, I didn't have to touch my certificates on Ubuntu.
Best of all, this isn't a workaround. It will download gems through
SSL and fail if there if there is a problem like a man in the middle
attack which is much better than just turning off security.
This has been fixed
http://guides.rubygems.org/ssl-certificate-update/
Now that RubyGems 2.6.x has been released, you can manually update to this version.
Download https://rubygems.org/downloads/rubygems-update-2.6.7.gem
Please download the file in a directory that you can later point to (eg. the root of your harddrive C:)
Now, using your Command Prompt:
C:\>gem install --local C:\rubygems-update-2.6.7.gem
C:\>update_rubygems --no-ri --no-rdoc
After this, gem --version should report the new update version.
You can now safely uninstall rubygems-update gem:
C:\>gem uninstall rubygems-update -x
Simple copy paste instruction given here about .pem file
https://gist.github.com/luislavena/f064211759ee0f806c88
For certificate verification failed
If you've read the previous sections, you will know what this means (and shame > on you if you have not).
We need to download AddTrustExternalCARoot-2048.pem.
Open a Command Prompt and type in:
C:>gem which rubygems
C:/Ruby21/lib/ruby/2.1.0/rubygems.rb
Now, let's locate that directory. From within the same window, enter the path part up to the file extension, but using backslashes instead:
C:>start C:\Ruby21\lib\ruby\2.1.0\rubygems
This will open a Explorer window inside the directory we indicated.
Step 3: Copy new trust certificate
Now, locate ssl_certs directory and copy the .pem file we obtained from previous step inside.
It will be listed with other files like GeoTrustGlobalCA.pem.
same problem but with different gem here:
Gem::RemoteFetcher::FetchError: SSL_connect returned=1 errno=0 state=SSLv3
read server certificate B: certificate verify failed
(https://bb-m.rubygems.org/gems/builder-3.0.0.gem)
An error occured while installing builder (3.0.0), and Bundler cannot continue.
Make sure that `gem install builder -v '3.0.0'` succeeds before bundling.
temporarily solution: gem install builder -v '3.0.0' makes it possible to continue bundle install
The simplest solution:
rvm pkg install openssl
rvm reinstall all --force
Voila!
This is How you fix this problem on Windows:
download .perm file then set the SSL_CERT_FILE in command prompt
https://gist.github.com/fnichol/867550
My permanent fix for Windows:
Download the CACert , save as C:\ruby\ssl_certs\GlobalSignRootCA.pem from http://guides.rubygems.org/ssl-certificate-update/
Create system variable named "SSL_CERT_FILE", set to C:\ruby\ssl_certs\GlobalSignRootCA.pem.
Try again: gem install bundler:
C:\gem sources
*** CURRENT SOURCES ***
https://rubygems.org/
C:\gem install bundler
Fetching: bundler-1.13.5.gem (100%)
Successfully installed bundler-1.13.5
1 gem installed
I get a slightly different error, though perhaps related, on Ubuntu 12.04:
Gem::RemoteFetcher::FetchError: SSL_connect returned=1 errno=0 state=unknown state: sslv3 alert handshake failure (https://d2chzxaqi4y7f8.cloudfront.net/gems/activesupport-3.2.3.gem)
An error occured while installing activesupport (3.2.3), and Bundler cannot continue.
Make sure that `gem install activesupport -v '3.2.3'` succeeds before bundling.
It happens when I run bundle install with source 'https://rubygems.org' in a Gemfile.
This is an issue with OpenSSL on Ubuntu 12.04. See Rubygems issue #319.
To fix this, run apt-get update && apt-get upgrade on Ubuntu 12.04 to upgrade your OpenSSL.
I was able to track this down to the fact that the binaries that rvm downloads do not play nice with OS X's OpenSSL, which is old and is no longer used by the OS.
The solution for me was to force compilation when installing Ruby via rvm:
rvm reinstall --disable-binary 2.2
Thx to #Alexander.Iljushkin for:
gem update --system --source http://rubygems.org/
After that bundler still failed and the solution to that was:
gem install bundler
I was getting a similar error. Here is how I solved this: In your path directory, check for Gemfile. Edit the source in the gemfile to http instead of https and save it. This might install the bundler without the SSL certificate issue.l
For Windows machine, check your gem version with
gem --version
Then update your gem as follow:
Running 1.8.x: download 1.8.30
Running 2.0.x: download 2.0.15
Running 2.2.x: download 2.2.3
Please download the file in a directory that you can later point to (eg. the root of your hard drive C:)
Now, using your Command Prompt:
C:\>gem install --local C:\rubygems-update-1.8.30.gem
C:\>update_rubygems --no-ri --no-rdoc
Now, bundle install will success without SSL certificate verification error.
More detailed instruction is here
This worked for me:
download latest gem at https://rubygems.org/pages/download
install the gem with gem install --local [path to downloaded gem file]
update the gems with update_rubygems
check that you're on the latest gem version with gem --version
I had to reinstall openssl:
brew uninstall --force openssl
brew install openssl
I was just recently faced with this issue and followed the steps outlined here. There might be a chance that you are not pointing to the right OpenSSL certificate. After running:
rvm osx-ssl-certs status all
rvm osx-ssl-certs update all
and
export SSL_CERT_FILE=/etc/ssl/certs/ca-certificates.crt
the bundle complete ran!
Download rubygems-update-2.6.7.gem .
Now, using your Command Prompt:
C:\>gem install --local C:\rubygems-update-2.6.7.gem
C:\>update_rubygems --no-ri --no-rdoc
After this, gem --version should report the new update version.
You can now safely uninstall rubygems-update gem:
C:\>gem uninstall rubygems-update -x
Removing update_rubygems
Successfully uninstalled rubygems-update-2.6.7
To note, if you're grabbing gems from a source which SSL cert is trusted by an internal certificate authority (or you are connecting to an external source through a company web proxy with SSL inspection), point your SSL_CERT_FILE env variable to your certificate chain. This most likely just requires exporting your root certificate from your certificate store (System Keychain on macOS) to an accessible location from your shell i.e.:
export SSL_CERT_FILE=~/RootCert.pem
If you're using rails-assets
If you were using https://rails-assets.org/ to manage your assets, no answers will help you. Even converting to http won't help.
The simplest fix is using this source instead, http://insecure.rails-assets.org. This has been mentioned in their homepage.
The only thing that worked for me on legacy windows system and ruby 1.9 version is downloading cacert file from
http://guides.rubygems.org/ssl-certificate-update/
And then running below command before running bundle install
bundle config --global ssl_ca_cert /path/to/file.pem

Ubuntu: "Could not find rails locally or in a repository"

I'm following these instructions to set up Ruby on Rails on my Ubuntu machine. For now at least, I'm planning to use Mongrel.
When I get to this step:
sudo gem install rails
...I get this message:
Bulk updating Gem source index for: http://gems.rubyforge.org/
ERROR: could not find rails locally or in a repository
What should I do next?
I would try to update gems first. The latest version is 1.3.3. You can do this on Ubuntu by either:
sudo gem install rubygems-update
sudo update_rubygems
or
sudo gem install rubygems-update
cd /var/lib/gems/1.8/gems/rubygems-update-*
sudo ruby setup.rb
basically, try again!
It could be a serious error, but in earlier versions ( I encountered this about 1 year ago or so ) it happend on the first try and when trying again the gem would eventually be found. I think it had something to do with the servers performance or such.
Using a recent version of rubygems is probably a good idea, and if it really won't work you can always get the .gem file from sourceforge directly and install from it.
For example with the file rails-2.3.2.gem:
gem install rails-2.3.2 –local
gem install rails --source http://gems.rubyonrails.org
