After upgrading to Rails 4.2, I was happy to try the new integrated web console, but I had some problems.
In the release notes for Rails 4.2, he mentions: "New applications built with Rails 4.2 now ship with the default web console gem."
Since I upgraded to 4.2, I assume that I still have to specify it in my Gemfile. Without adding it to your Gemfile, the rails just give me an "undefined local variable or the" console "method, so I assume that it is.
As soon as I added the gem 'web-console', '~> 2.0' to the Gemfile and started the rails server, now I get:

I googled around and did not find much. Any advice is appreciated.
Thank!
