title: Rails + Twitter Bootstrap: File to import not found or unreadable: twitter/bootstrap
body: <p>I am trying to set up Rails app with Twitter Bootstrap (the gem <code>twitter-bootstrap-rails</code>), but I still cannot get over the error</p>
  
  <pre><code>File to import not found or unreadable: twitter/bootstrap.
  </code></pre>
  
  <p>I found this issue on official Github of the gem, but none of solution from there have worked for me.
  Here's my setup:
  <strong>Gemfile</strong></p>
  
  <pre><code>gem "twitter-bootstrap-rails"
  gem 'font-awesome-rails'
  gem 'sass-rails',   '~&gt; 3.2.3'
  group :assets do
    #gem 'sass-rails',   '~&gt; 3.2.3'
    gem 'coffee-rails', '~&gt; 3.2.1'
    gem 'therubyracer', :platforms =&gt; :ruby
    gem 'uglifier', '&gt;= 1.0.3'
  end
  </code></pre>
  
  <p><strong>application.css</strong></p>
  
  <pre><code> *= require_self
   *= require bootstrap_and_overrides
   *= require font-awesome
   *= require_tree .
  </code></pre>
  
  <p><strong>bootstrap_and_overrides.css.sass</strong></p>
  
  <pre><code>@import "twitter/bootstrap";
  @import "twitter/bootstrap/bootstrap";
  @import "twitter/bootstrap/responsive";
  
  // Font Awesome
  @import "fontawesome";
  
  // Glyphicons
  @import "twitter/bootstrap/sprites.scss";
  </code></pre>
  
  <p>What am I missing for correct set up?</p>
  
  <p>Thanks</p>
