## Completely Removing RVM

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 sudo rm -rf /usr/local/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 ```

There is a function to add managers, however it requires that Mult-User is enabled from a super user installation.

From the RVM guided installation:

    After following above instructions for Multi-User.

    For each user that want to use RVM, an additional command needs to be run (once) for each user:

rvm user gemsets

but the Multi-User function should have been enabled first:

The (Multi-User) rvm function will be automatically configured for every user on the system if you install with sudo.
