  Bundle complete! 14 Gemfile dependencies, 59 gems now installed.
  Gems in the group production were not installed.
  Use `bundle show [gemname]` to see where a bundled gem is installed.
  Post-install message from rdoc:
  Depending on your version of ruby, you may need to install ruby rdoc/ri data:
  
  &lt;= 1.8.6 : unsupported
   = 1.8.7 : gem install rdoc-data; rdoc-data --install
   = 1.9.1 : gem install rdoc-data; rdoc-data --install
  &gt;= 1.9.2 : nothing to do! Yay!

  <p>All good till here.</p>
  
  <p>Then i added the code <code>@import "bootstrap";</code> into my styles.css.scss file.
  I restarted the server for the changes to reflect in localhost:3000
  Then this happens:</p>
  
  <pre><code>    rails server
  Warning: Running `gem pristine --all` to regenerate your installed gemspecs (and deleting then reinstalling your bundle if you use bundle --path) will improve the startup performance of Spring.
  Could not find autoprefixer-rails-5.1.7 in any of the sources
  Run `bundle install` to install missing gems.
  </code></pre>
  
  <p>I tried running 'bundle install' but to my dismay the same error crept up again and again.
  So in a jist, the server doesn't start citing "it couldn't find autoprefixer-rails-5.1.7 gem " but if you check the script above it has actually installed it.</p>
  
  <p>Please help me fix this. </p>
