Use the gemset empty command:

rvm gemset empty mygems

You need to specify the gemset you want to empty. It's not enough just to "rvm use [gemset_name]". You need to "rvm gemset empty [gemset_name]". – refaelos Nov 29 '11 at 10:22
I suppose if you have many gems, it could take a while to uninstall them all. – Andy Lindeman Jun 10 '12 at 21:18

Incidentally right now I am able to run `rvm gemset empty` and it clears the current gemset. – Ibrahim Jan 10 '13 at 05:19

This command removes all the ruby gems installed locally in 1-step Works well in Ubuntu 10.10

gem list | cut -d" " -f1 | xargs gem uninstall -aIx

PS - removes all local gems. Use sudo accordingly.

gem also has a --no-versions flag, which is nice: `gem list --no-versions | xargs gem uninstall -aIx` – trisweb Nov 20 '12 at 16:32

rvm gemset empty <gemset name>

This will remove all gems from your mentioned gemset.

rvm gemset empty <gemset> works, but only if you specify a gemset name.

If you want to empty the default gemset, you need to pass an empty string for the gemset name.

rvm gemset empty mygems ""

Isn't removing all the gems out of a gemset essentially the same operation as deleting a gemset and then adding it back? Why not just do this:

$ rvm gemset mygemset
$ rvm gemset delete mygemset
$ rvm gemset create mygemset

Yes, essentially it's the same. But I was wondering if there is a way to do this without deleting the gemset. When you delete a gemset, are the gems removed too or are they saved to a cache? – Nerian Jan 14 '11 at 17:02

I'm pretty sure they're completely removed. For example, I have a gemset named `jruby-1.5.6@radiant`. All the gems are located here: `/Users/dparoulek/.rvm/gems/jruby-1.5.6@radiant`. When I do `rvm gemset radiant`, then it warns you to make sure, and then deletes the entire `/Users/dparoulek/.rvm/gems/jruby-1.5.6@radiant` directory. – Upgradingdave Jan 14 '11 at 17:39
This would be about the same I guess. I was looking for an alternative because I wanted to remove all the gems from the global gemset so that I could stop new gemsets from "inheriting" the gems from the global gemset. – Moiz Raja Nov 27 '11 at 20:42

This is the safest way to uninstalling all gems of a gemset

Step 1

If you gem version is less then 2.1.

gem update --system

gem --version

Step 2

gem uninstall --all
