title: Missing Windows module in Flask app running on Ubuntu Droplet
body: <p>I'm trying to run a Flask app on an Ubuntu Droplet but when I try to run the app with <code>python app.py</code> I get the following traceback:</p>
  
  <pre><code>* Running on http://0.0.0.0:4000/ (Press CTRL+C to quit)
   * Restarting with stat
  Traceback (most recent call last):
    File "app.py", line 49, in &lt;module&gt;
      app.run('0.0.0.0', port=4000, debug=True)

      __import__(name)
  ImportError: No module named _winreg
  </code></pre>
  
  <p>I can't install the package with pip or apt-get since I'm pretty sure this is a Windows-specific module. Is there any way I can get around this?</p>
