问题
I'm having some problems with ruby gems. I'm trying to install the gem hitimes although after trying to install it (even using sudo) I get this error: http://cl.ly/Hvlf.
Could it be that I already have it installed because I've tried a few times now. Is there a way to uninstall a gem?
The gem can be found here on RubyGems.org and I've even tried to download the .gem file and install it that way but had no luck.
