title: What do I add to my requirements.txt in Django directory in order to push it to Heroku?
body: <p>I am new to programming/web development and I want to push a Django directory to heroku. But every time I enter "git push heroku master" into my command line I get the same error:</p>
  
  <pre><code>"Could not find a version that satisfies the requirement bonjour-py==0.3 (from -r /tmp/build_602f#############86ff270e/requirements.txt (line 3)) (from versions: )"
  </code></pre>
  
  <p>I activated the virtual environment, but to no avail. Now I assume that the problem might be that my requirements.txt file does not contain anything (as I thought there would not be a reason for that, anyway). Still, I wonder what <code>"bonjour-py==0.3"</code> is and how that could be fixed. Thank you very much for your help!</p>
