Minitest 4.7.5 error in bundler when starting rails

Question

I'm brand new to rails, and litelarry am trying to set up a helloworld app to get my feet wet.

I installed homebrrew, ruby build and rbenv. I installed pow, and then unistalled it. basically played around, and then worked out how to make an application, and wonderful. I created helloworld.

I know minitest (5.0.8, 4.3.2) is installed in my home directory.

I cd into the hellowworld directory, and try to make the app active by typing rails -s.

I get this minitest error?

As far as I can see it relates to bundler, minitest4.7.5 is missing which I get. BUT how do I see that minitest 5.0 etc is installed.

Any help would be greatly appreciated.

Per this link regarding bundler version 1.5.0, you should upgrade your bundler to version 1.5.1 or higher to fix a nasty little bug that surfaces with default gems in Ruby 1.9 and 2.0. I simply ran gem update bundler before running bundle install and everything seems fine now.
