RVM: Uninstalling all gems of a gemset

Question

Use the gemset empty command:

rvm gemset empty mygems

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.

rvm gemset empty <gemset name>

This will remove all gems from your mentioned gemset.

you can also use rvm --force gemset empty

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

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 ""

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
