- $ rbenv versions
List all ruby versions known to rbenv, asterick represents the current version
* 2.0.0-rc2 (set by /home/jude/.ruby-version)
2. $ rbenv local 1.9.3-p385
Sets the specified ruby version locally
3. $ rbenv global 1.9.3-p385
Sets the specified ruby version globally
Also check that you have the following in your ~/.bash_profile or ~/.bashrc if using bash
eval "$(rbenv init -)"
NOTE: Make sure it's the last setting in your ~/.bash_profile . I ran into an issue where I installed a program that updated my .bash_profile and reset PATH.
