Uninstall Rails completely

Question

I’m trying to uninstall Rails completely, but I can’t get the grip of it.

Here’s what I tried:

$ gem update
rails 4.0.0.beta1 instal

If you are using rvm, you can uninstall all gems by deleting .gem directory in you $HOME

rm -rf ~/.gem

or uninstall only rails:

gem uninstall -a rails

or if you installed using sudo:

sudo gem uninstall -a rails
