I'm developing a flask.app that uses web socket functionality and installed flask-socket to provide that. So the flask-socket developer recommends gunicorn as web server. My question is now how to connect the remove debugger of pycharm with gunicorn to intercept the execution with breakpoints.

pycharm flask python

My case for PyCharm 2018.1.3 Professional:

  1. Go to run/debug configurations creating-and-editing-run-debug-configurations

  2. Choose new "Python" config

  3. Script path: your_path_to_/venv/bin/gunicorn
  4. Parameters(for my case): -b :5001 --access-logfile - --error-logfile - "run:create_application()"
  5. Python interpreter: your venv python version for project
  6. Working directory: path to your project
  7. Save and press DEBUG (Shift+F9)
  8. be happy!

I was trying to debug on Pycharm 2020.2.1 and the break points weren't correctly working even though the Gevent compatible debugging was enabled. It turned out that I had to disable Cython for my run configuration via setting the environment variable as described here to make it work.
