OS: Mac OS 10.9.2
Ruby: 2.0.0(before update to 2.1.1)
Rails: 4.0.4
Problems
I updated ruby 2.0.0 to 2.1.1 and add to Gemfile ruby '2.1.1'.
Then problem has occurred.
When execute rails s, it fails and message
Your Ruby version is 2.0.0, but your Gemfile specified 2.1.1
is displayed.
Solution
I tried many things, but I can't solve.
But when execute bundler update, I finally resolved that problem.
