There are times when you might find yourself needing to completely remove RVM from your system. You can easily do so with a few simple commands.
rm -rf ~/.rvm* sudo rm -rf /etc/rvm* sudo groupdel rvm
You'll also need to remove the following line from your .bashrc file & reload load BASH
[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" # Load RVM function
If you're going from site-wide install back to a single user install, you'll also want to do the following:
sudo rm /etc/profile.d/rvm.sh sudo rm /usr/share/ruby-rvm
