export http_proxy=http://xxx.xxx.xxx.xxx:port_no/
export https_proxy=https://xxx.xxx.xxx.xxx:port_no/

rvm – Branch origin/ruby_2_1_0 not found.


You are trying to install the new ruby in your ubuntu rvm installation with rvm install 2.1 but you are getting the error:

Branch origin/ruby_2_1_0 not found.
There has been an error while checking out branch ruby_2_1_0.
Halting the installation.                               
There has been an error fetching the ruby interpreter. 
Halting the installation.


If you are careful and you notice a warning message as:

Warning, new version of rvm available '1.25.26', 
you are using older version '1.24.8'.

then you would need to update your rvm installation to the latest one with:

rvm update

And then you should be able to install the latest ruby version with:

rvm install 2.1

Dreamhost keeps asking for password when installing rvm ruby version


After installing rvm on dreamhost, when trying to install any ruby version afterwards, there is a prompt for password, and when entering the user’s password there is the message that the user is not in the sudoers list.


To be able to install the rvm ruby version you would like you should be installing them by using the following which is based on the answer here :

rvm list remote

and then:

rvm mount -r https://rvm.io/binaries/debian/6/x86_64/ruby-2.0.0-p247.tar.bz2 --verify-downloads 1

rvm “You need to change your terminal emulator preferences to allow login shell.”


After a new rvm installation in an (k)ubuntu system you get the following error from rvm when trying to switch between rubies:

You need to change your terminal emulator preferences to allow login shell.
Sometimes it is required to use `/bin/bash --login` as the command.
Please visit https://rvm.io/integration/gnome-terminal/ for a example.


As the message suggests you can change the setting in your terminal which is fine if you are using the gnome-terminal by going to the link provided:

Please visit https://rvm.io/integration/gnome-terminal/ for a example.

but if you are using Konsole in KDE you need to go to a different link that explains the change in the settings:

Please visit http://rvm.io/integration/konsole/ for a example.

rails `require’: cannot load such file — mysql2/mysql2 (LoadError)


You want to use a different ruby version from the one you have initially installed and build your application with, but when you change it in your rvm installation you get the following error:

..gems/mysql2-0.3.13/lib/mysql2.rb:8:in `require': cannot load such 
file -- mysql2/mysql2 (LoadError)


To make it work again you will have to uninstall the mysql2 gem and install it again in the new ruby version with the option –platform=ruby.

rvm use ruby-2.0.0-p247
cd my_project
rails s
..... gems/mysql2-0.3.13/lib/mysql2.rb:8:in `require': cannot load 
such file -- mysql2/mysql2 (LoadError)
gem uninstall mysql2
gem install mysql2 --platform=ruby
rails s

RVM and RubyGems versions


You would like to upgrade your rubygems version from 1.8.17 to the latest version 2.0.7 for example.


You can upgrade to a specific or the latest gem version and relate that to a specific rvm ruby that you have installed.
So if for example you have ruby-1.9.3-p327 and ruby-2.0.0-p247, you can have different gem version (or the same if you want) for each ruby version.

To upgrade to the latest one in the ruby-2.0.0-p247 for example you could do the following:

rvm list
rvm use ruby-1.9.3-p327
gem -version
rvm use ruby-2.0.0-p247
gem --version
gem update --system
gem --version
rvm use ruby-1.9.3-p327
gem --version

Getting rails console on an amazon aws server when using rvm


You would like to get access to your rails application console on an Amazon ec2 instance, and you are also using rvm.


  • Login with ssh to your server as normal:
    ssh name@myserver.com -i amazon_key
  • Go to your application’s current folder:
    cd /my/project/directory/current/
  • Run the following replacing the environment with your specific environment (ie production,beta,staging etc):
    bundle exec rails c environment

$rvm_path (/home/ubuntu/.rvm/) does not exist. error


When you want to use the capistrano recipe to deploy to a vagrant virtual box as described in ‘Deploying Rails’, and after you have corrected the rvm_path as described here, you get the following error message:

$rvm_path (/home/ubuntu/.rvm/) does not exist.


Make sure that after adding the rvm_path add also the following to the deploy.rb file, since rvm is installed system wide.

set :rvm_type, :system

Suggestion from here.

.rvm/bin/rvm-shell: No such file or directory error


When trying to set up the capistrano deploy recipe to deploy to the vagrant virtual box as described in ‘Deploying rails’, you get the error:

.rvm/bin/rvm-shell: No such file or directory

when you have installed rvm system wide on the virtual box.


Make sure that you add the following into your deploy.rb file to set up the path for rvm:

set :rvm_bin_path, "/usr/local/rvm/bin"
