title: heroku/python buildpack for node.js app get rejected
body: <p>I have an Node.js app with Python scripts that I am trying to deploy to Heroku.</p>
  
  <p>Every time I try to add the <code>heroku/python</code> buildpack the <code>git push</code> gets rejected.</p>

  <p>Without the <code>heroku/python</code> buildpack the push works fine. I think I need that buildback for my Python scripts work on web. </p>
  
  <p>My app runs fine locally but everything related to Python is not working when deployed. I use Python 3.7.3 64-bit version.
  I have runtime.txt and requirements.txt in root of my app.</p>
  
  <p>My <code>runtime.txt</code> file:</p>
  
  <pre><code>python-3.7.3
