rbenv is a tool for simple Ruby version management.

To install rbenv, please refer to the Readme.

See Why rbenv?

1. Check that rbenv is in your PATH:

   command which rbenv
   

2. Check that rbenv's shims directory is in PATH:

   echo $PATH | grep --color=auto "$(rbenv root)/shims"

   If not, see the rbenv init step in installation instructions.

Typically it's one of the following:

• bash: ~/.bash_profile
• zsh: ~/.zshenv
• other: ~/.profile

If your .bash_profile isn't taking effect, create this .bashrc file:

# invoked for non-login, interactive shells
[ -n "$PS1" ] && source ~/.bash_profile

If you already have a .profile file, it might be best to not create .bash_profile or .bashrc, but put rbenv configuration in .profile.

For zsh, you may experience better results with .zshrc instead of .zshenv.

See Unix shell initialization for more info about how config files get loaded.

Rubinius in 1.9 mode uses a separate bin directory for executable binstubs. To compensate for that, use the rbx 2.0 dev fix plugin.
