title: Capistrano error: Sprockets::FileNotFound: couldn't find file 'bootstrap-sprockets'
body: <p>I am using the <code>gem "bootstrap-sass"</code> gem.</p>
  
  <p>In <code>application.js</code>:</p>
  
  <pre><code>//= require jquery
  //= require jquery_ujs
  //= require bootstrap-sprockets
  //= require_tree .
  </code></pre>
  
  <p>in <code>application.css.scss</code>:</p>
  
  <pre><code>@import "bootstrap-sprockets";
  @import "bootstrap";
  </code></pre>
  
  <p>On localhost works everything perfectly, but when I try to deploy the code using <code>Capistrano</code>, I get this error message:</p>
  
  <pre><code>  ...

  <p>The line <code>#17</code> points here:</p>
  
  <blockquote>
    <p>//= require bootstrap-sprockets</p>
  </blockquote>
  
  <p>Why is that &amp; what am I missing here?</p>
