title: Action Controller: Exception caught - turbolinks issue?
body: <p>I am following Michael Hartl's Rails guide, and when I load localhost:3000 I get the following error messages in the browser:</p>
  
  <pre><code> Sprockets::FileNotFound in Static_pages#home
  
   Showing /home/jonathan/Desktop/railsTut/sample_app/app/views/layouts/application.html.erb   where line #6 raised:
  
  couldn't find file 'turbolinks'
   (in /home/jonathan/Desktop/railsTut/sample_app/app/assets/javascripts/application.js:16)
  </code></pre>
  
  <p>This is my file from the aformentioned message</p>
  
  <pre><code>// This is a manifest file that'll be compiled into application.js, which will include     all the files
  // listed below.

  <p>also, I am not sure if it is related, but here is my Gemfile:</p>
