Ruby 2.2.2 and Rails 4.2.1 railties or spring dependency issues

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

/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/2.0.0/rubygems/dependency.rb:296:in

Any insight into this?

By the way, I am using chruby if that helps anyone to understand the
issues

Sounds like you need to run ‘gem install rails’ again. It will find the
missing dependencies, including railties, and reinstall them.

Great answer, that sounds like the problem… and now it works!
