Ruby on Rails

Ok, here's the story so far.  Last night I passed rails new and it worked but I got a message at the end that i should be using Ruby 2.2.2 to ensure the best performance, I think because of spring.  I switched to Ruby 2.2.2 so this isn't as much of a question about spring but I figured I should mention it as part of the process of how I got to being on Ruby 2.2.2

Now that I am, when I do rails new the only thing that happens is I get this feedback

Any insight into this?
