title: fixing css after rake:assets precompile - how to not run capistrano
body: <p>I recently changed an image on the landing page of my herokuapp built in rails. I realized that everything worked fine except that the landing page threw a 500 error. Upon some research I realized i should run <code>RAILS_ENV=production bundle exec rake assets:precompile</code></p>
  
  <p>After doing so, the images and some of the styling came back but some of it is still screwy and I cannot understand why.</p>
  
  <p>I've read through just about every stackoverflow thread, the <a href="http://guides.rubyonrails.org/asset_pipeline.html" rel="nofollow">rails guide on the asset pipeline</a>, and others but I can't get it to work. I've amended the files that need amending 
  as far as I know but nothing is working to make the styling revert to how it should be.</p>
  
  <p>However, on the rails guide it notes that there are two caveats to locally precompile:</p>
  
  <blockquote>
    <p>You must not run the Capistrano deployment task that precompiles
    assets. You must change the following two application configuration
    settings. In config/environments/development.rb, place the following
    line:</p>
    
    <p>config.assets.prefix = "/dev-assets"</p>
  </blockquote>
  
  <p>I did the change within development.rb but I am not sure on how I can not run Capistrano. I dont think I'm doing that so maybe it's throwing some things off - idk, but each time I try to recompile now, the rake aborts. Any help is very much appreciated.</p>
