title: "rails generate" not working
body: <p>When using ruby 2.1.0 (or 2.1.1) and I type <code>rails g</code> nothing happens. It simply hangs.
  But when I change to 1.9.3, using <code>rvm use 1.9.3</code> it works as expected.</p>
  
  <p>How can I debug this? What might be causing this command to hang, only on ruby > 2.0.0?</p>
  
  <p>I have tried reinstalling both rails and ruby!</p>
