title: Why won't Heroku accept my Gemfile.lock in Windows?
body: <p>I have a rails application that I deploy on Heroku. I'm using several different machines, and I noticed that when I add new dependencies (so that <code>Gemfile.lock</code> is rebuilt) and do <code>bundle install</code> on my Windows computer at home, push to Heroku fails with the following error:</p>
  
  <pre><code>   Unresolved dependencies detected; Installing...
     Windows Gemfile.lock detected, ignoring it.
     You have modified your Gemfile in development but did not check
     the resulting snapshot (Gemfile.lock) into version control
     ...
  </code></pre>
  
  <p><code>Gemfile.lock</code> IS under version control, but Heroku appearently chooses to ignore it since it's created in Windows, and then complains that it's missing seconds later. Why does this happen? And how can I solve it?</p>
