Shame about this tutorial
It's a real shame that this tutorial is not updated. As when I try to run bundle I get this error
An error occurred while installing json (1.8.1), and Bundler cannot continue. Make sure that `gem install json -v '1.8.1'` succeeds before bundling.
It basically means that app is not usable. It would have been great if she started from scratch.

bundle update && bundle install to see if you can get gem to properly install the json version you need.
I ran 'bundle update json' and that worked fine for me...gdluck!
