To Remove RVM

  • rvm implode
Note you may need to manually remove /etc/rvmrc and ~/.rvmrc if they exist still.
Please check all .bashrc .bash_profile .profile and .zshrc for RVM source lines and delete or comment out if this was a Per-User installation.
Also make sure to remove `rvm` group if this was a system installation.
Finally it might help to relogin / restart if you want to have fresh environment (like for installing RVM again).
  • Remove the following:
  • rm /etc/rvmrc
  • rm ~/.rvmrc
  • Check .bashrc
  • Check .bash_profile
  • Check .profile
  • Check .mkshrc
  • Check .zshrc to remove all references to rvm
