title: Failed to deploy Rails app with gem bootstrap-sass 3.0.3.0 on heroku
body: <p>I have a rails application that I wanted to upgrade from bootstrap-sass 2 to bootstrap-sass 3</p>
  
  <p>After modifying some css class name, my application worked perfectly on my machine.</p>
  
  <p>I removed the @import bootstrap-responsive ( because bootstrap is natively responsive since 3.0 ) I updated my gemfile and my bundle BUT when I try to deploy my application on Heroku I have the following error : </p>
  
  <p><code>
  AssetSync: using /tmp/build_68121564-cc6f-46c8-86d7-ad9ccb180ea1/config/initializers/asset_sync.rb
         rake aborted!
         File to import not found or unreadable: bootstrap-responsive.
         Load paths:
         Sass::Rails::Importer(/tmp/build_68121564-cc6f-46c8-86d7-ad9ccb180ea1/app/assets/stylesheets/developers.css.sass)
  </code></p>
  
  <p>What I tried so far : </p>
  
  <ul>
  <li>Remove gem bootstap-sass from the asset group (didn't work )</li>
  <li>I tried the rake tmp:clear command (didn't work either )</li>
  <li>Bundle updated and bundle installed everything again ( still not working )</li>
  </ul>
  
  <p>What should I do ? 
  The problem is clearly due to some temp files but even after cleaning them I can't push my app on heroku.</p>
