rbenv is a tool for simple Ruby version management.

To install rbenv, please refer to the Readme.

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.

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.
