Error Installing Cocoapods

Try this Stack Overflow answer.

It seems like you may not have Ruby installed.

Here's a checklist that might help:

1. Do you have multiple versions of Ruby? Do you have rvm or rbenv installed? If so, you have to make sure you are installing the CocoaPod gem to the right version.
2. Do you have the latest version of Xcode?
3. Do you have multiple versions of Xcode? If you do, then use the xcode-select to select the latest version of Xcode.
4. Finally, here's another workaround that helped others: https://gist.github.com/goshakkk/5763489
