Error Messages

If you receive the message:

You have not agreed to the Xcode license agreements. You must agree to both license agreements below in order to use Xcode.

run sudo gcc, hit Enter, type q, type agree, type Enter

Should be gem install bundler.

If you have installed rbenv through brew, it is best to run this first:

brew upgrade rbenv ruby-build

I found not all of the ruby versions available for install were updated correctly without running that command first.

The command should not be username-specific. It should be:

source ~/.rvm/scripts/rvm
