title: Ruby on Rails console is hanging when loading
body: <p>For whatever reason, the Ruby on Rails console refuses to start; it just hangs. I haven't made any changes to my code, and other projects using the same version of Ruby and Ruby on Rails have no issue. When I finally <kbd>Ctrl</kbd> + <kbd>C</kbd> I get this stack trace, which points to Spring.</p>
  
  <p>I can't explain why this is happening from one moment to the next, where it was working fine. I have cleared out all the gems through RVM and reinstalled all through bundle command, but still no luck. Any ideas would be appreciated.</p>
  
  <p>Also the Ruby on Rails server has no issue so as far as I can tell. The issue is project related, however no code has changed, and it's only the Ruby on Rails console that has the issue.</p>
  
  <p>Ruby 2.1.2 <br/>
  Rails 4.1.4</p>
