问题
I'm trying to install a Cocoapods plugin and my Mac's gem and Ruby seem completely broken.
Here's my output for 'pod install':

---------------------------------------------
[!] Your Podfile requires that the plugin `cocoapods-keys` be installed. Please install it and try installation again.
I have installed cocoapods-keys with 'sudo gem install cocoapods-keys', but I have no idea why my pod install is turning up all these errors. I'm tempted to remove my system Ruby and start over, but it seems from other answers like that's a bad idea.
Can someone help?
