Uninstall Rails 3 with dependencies?

Question

I like that Rails 3 is so easy to install: gem install rails --pre, and all of the dependencies are automatically installed for you. But, what about uninstalling it

Answer 1

Check your currently installed version(s):

gem list -d rails

Then uninstall the version(s) you don't want:

sudo gem uninstall rails -v 3.0.0.beta3
sudo gem uninstall actionmailer -v 3.0.0.beta3

etc.

I'm still trying to figure out how to completely remove rails 3.0.0.beta3 and all its deps.
