Linux Non VM


To build and install Ruby yourself on Linux, first make sure that you have followed the instructions on the Linux Downloads page.

If you run into errors at any step here, please ask an instructor or TA to help diagnose the issue.

Open your command line and cd to the directory where you put chruby and ruby-install.

Build Tools

cd to the chruby directory that you cloned with Git. Run:

make install

cd to the ruby-install directory that you cloned with Git. Run:

make install



ruby-install ruby 2.0

This will download and build Ruby, which will take a while.

Run: ruby -v

If everything is set up, you'll see:

ruby 2.0.0p451 (2014-02-24) [i686-linux]
  1. Add chruby to your shell

    echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bash_profile
    echo 'eval "$(rbenv init -)"' >> ~/.bash_profile

    Linux Mint and Ubuntu 10.10: Modify your ~/.bashrc file instead of ~/.bash_profile. Zsh: Modify your ~/.zshenv file instead of ~/.bash_profile.

  2. Restart your shell so the path changes take effect. You can now begin using rbenv.

    exec $SHELL
  3. Close an re-open your terminal and confirm Ruby is installed properly

    ruby --version

    You should get something similar to ruby 2.0.0p451 (2014-02-24) [i686-linux] If you do not see ruby 2.0.0 please call in an instructor to help diagnose the installation issue.

  4. Install Rails and other supporting gems

    gem install rails -v 4.0.5
    gem install protected_attributes

Congratulations, you now have the Ruby development environment up and running. Now go forth and do something awesome with it!
