How to completely uninstall rails 3.0.0.beta3 and all its dependencies?

Question

If I do sudo gem uninstall rails -v 3.0.0.beta3, it uninstalls rails but leaves the beta3 versions of activerecord, actionmailer, etc. How do I completely uninstall rails 3.0.0.beta3 and all its dependencies automatically? I would like a clean slate for the RC and final releases.

well sure, if you want to do it the hard way! i was hoping dependencies also worked for UNinstall :) – Mark Richman Jun 10 '10 at 19:27

@Mark Richman: RubyGems doesn't track which gems were installed manually and which ones were installed automatically as dependencies. Therefore, it simply *cannot* know which ones are still needed. – Jörg W Mittag Jun 10 '10 at 23:16

If your situation is that you have installed beta 4 and want to get rid of beta 3, you can simply run

gem cleanup

which removes all but the latest version of all your gems (wiping out beta 3 and leaving you with beta 4).

You can list out all the dependencies of a specific rails version

$ gem dependency rails -v 3.1.0
Gem rails-3.1.0
  actionmailer (= 3.1.0)
  actionpack (= 3.1.0)
  activerecord (= 3.1.0)
  activeresource (= 3.1.0)
  activesupport (= 3.1.0)
  bundler (~> 1.0)
  railties (= 3.1.0)

Unfortunately there isn't any single command to remove all dependencies. You have to manually remove each dependent gem

$ gem remove activerecord -v 3.1.0

You can also view reverse dependencies by using the **-v** flag

    $ gem dependency rails -r

you can't do it automatically unless you write your own script wrapper around the gem uninstall command

just manually do gem uninstall on the other files like activerecord, activesupport, etc...
