How can I remove RVM (Ruby Version Manager) from my system?

回答1:

There's a simple command built-in that will pull it:

rvm implode

This will remove the rvm/ directory and all the rubies built within it. In order to remove the final trace of rvm, you need to remove the rvm gem, too:

gem uninstall rvm

If you've made modifications to your PATH you might want to pull those, too. Check your .bashrc, .profile and .bash_profile files, among other things.

You may also have an /etc/rvmrc file, or one in your home directory ~/.rvmrc that may need to be removed as well.

If the other answers don’t remove RVM throughly enough for you, RVM’s Troubleshooting page contains this section:

How do I completely clean out all traces of RVM from my system, including for system wide installs?

Here is a custom script which we name as cleanout-rvm. While you can definitely use rvm implode as a regular user or rvmsudo rvm implode for a system wide install, this script is useful as it steps completely outside of RVM and cleans out RVM without using RVM itself, leaving no traces.

#!/bin/bash
/usr/bin/sudo rm -rf $HOME/.rvm $HOME/.rvmrc /etc/rvmrc /etc/profile.d/rvm.sh /usr/local/rvm /usr/local/bin/rvm
/usr/bin/sudo /usr/sbin/groupdel rvm
/bin/echo "RVM is removed. Please check all .bashrc|.bash_profile|.profile|.zshrc for RVM source lines and delete
or comment out if this was a Per-User installation."

When using implode and you see:

Psychologist intervened, cancelling implosion, crisis avoided :)

Then you may want to use --force

rvm implode --force

Then remove rvm from following locations:

rm -rf /usr/local/rvm
sudo rm /etc/profile.d/rvm.sh
sudo rm /etc/rvmrc
sudo rm ~/.rvmrc

Check the following files and remove or comment out references to rvm

~/.bashrc 
~/.bash_profile 
~/.profile 
~/.zshrc
~/.zlogin

Comment-out / Remove the following lines from /etc/profile

 source /etc/profile.d/sm.sh
 source /etc/profile.d/rvm.sh

/etc/profile is a readonly file so use

sudo vim /etc/profile

And after making the change write using a bang!

:w!

Finally re-login / restart your terminal.

In addition to @tadman's answer I removed the wrappers in /usr/local/bin as well as the file /etc/profile.d/rvm.

The wrappers include:

erb
gem
irb
rake
rdoc
ri
ruby
testrb

A lot of people do a common mistake of thinking that 'rvm implode' does it . You need to delete all traces of any .rm files . Also , it will take some manual deletions from root . Make sure , it gets deleted and also all the ruby versions u installed using it .

回答6:

Remove the RVM load script from /.bash_rc or /.zsh_rc, then use:

rm -rf /.rvm

Or:

rvm implode

回答7:

Run the following command

rvm implode

Now you need to unistall the rvm gem:

gem uninstall rvm

Check if there are any remaining rvm files in your home directory, if yes remove them.

Go to the home directory and list all hidden files

ls -a

rm  .rvm
rm  .rvmrc

回答8:

Note that if you installed RVM via apt-get, you have to run some further steps than rvm implode or apt-get remove ruby-rvm to get it to really uninstall.

See "Installing RVM on Ubuntu".

回答9:

If you're still getting a env: ruby_executable_hooks: No such file or directory when calling some Ruby package, that means RVM left a little gift for you in your $PATH.

Run the following to find the offending scripts:

grep '#!/usr/bin/env ruby_executable_hooks' /usr/local/bin/*

Then rm all the matches. You'll have to reinstall all of those libraries with an RVM-free gem, of course.

回答10:

For other shell newbies trying to fix the PATH variable

After following instructions in accepted answer, check and modify your PATH variable if necessary :

env | grep PATH 

if you see "rvm" anywhere, you need to figure out where you are setting PATH and modify. I was setting it in 3 files - so check all the following files:

vim .bashrc  

Delete the lines in the file referencing rvm using the dd command. :wq to save and exit.
source .bashrc to "reload"

Repeat this process (starting with the vim command) for .profile and .bash_profile
