In the terminal: gem install rails -v 4.1.4 - now you will have the latest Rails available for your applications

When creating the app for the first time, you can specify the version of Rails you want to use (it has to be installed using the method above): rails _4.1.4_ new odot

To make sure everything worked correctly, check if Rails 4.1.4 is specified in the Gemfile. Also, I suggest using RSpec version that Jason uses, not the newest (there are some differences and not all the Jason's code may work).

Thanks again Maciej! Looks like what you suggested worked! All your answers have been very helpful!
