title: What to do if "git push heroku master" failed?
body: <p>I have a working Rails app on my local Windows XP machine. I want to upload it on Heroku. I follow this tutorial <a href="https://devcenter.heroku.com/articles/rails3" rel="nofollow">https://devcenter.heroku.com/articles/rails3</a>.</p>
  
  <p>When I ran <code>git push heroku master</code>, it failed:</p>
  
  <pre><code>-----&gt; Ruby/Rails app detected
  -----&gt; WARNING: Removing `Gemfile.lock` because it was generated on Windows.
         Bundler will do a full resolve so native gems are handled properly.
         This may result in unexpected gem versions being used in your app.

  <p>What do I have to do now? </p>
  
  <p>I saw the log, there are some issues like these ones:</p>

  </code></pre>
  
  <p>I removed <code>resize.rb:23</code> file. It is for re-sizing images, app doesn't use, I just left it there on development and forgot to delete when uploaded my app on Heroku. On my local machine it is not run by itself, but Heroku for some reason started it. There was a function call to <code>C:\sbox\ruby\cards2</code> location and that's why the error happened, I thought. Ok, I removed the file. Do not know, though, about other issues.</p>
  
  <p>But what do I need to do now? How to start the process again? I ran <code>git push heroku master</code> again but got:</p>
  
  <pre><code>C:\sbox\ruby\Sites\Heroku\Cards&gt;git push heroku master
  Everything up-to-date
  </code></pre>
  
  <p>Nothing works but Heroku says that everything is up-to-date. </p>
  
  <p>Is there a way to see all my app files on Heroku server the way you can see your files on shared hosting?</p>
