RVM: Uninstalling all gems of a gemset

问题

I have global gems and various gemsets. I want to remove all gems of a gemset. Is there a way do to this, besides uninstalling the gemset?

回答1:

Use the gemset empty command:

rvm gemset empty mygems

回答2:

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.

回答3:

rvm gemset empty <gemset name>

This will remove all gems from your mentioned gemset.

回答4:

you can also use rvm --force gemset empty

回答5:

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 ""

回答6:

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

回答7:

gem update --system

gem --version
