I am attempting to deploy a django project to Heroku and I'm getting slapped left and right with errors but hopefully this is the last one.

And when I try to run the program in a virtual environment on my local machine using the command heroku local:

6:06:35 PM web.1 |  [2022-03-07 18:06:35 -0400] [33412] [INFO] Starting gunicorn 20.1.0
6:06:35 PM web.1 |  [2022-03-07 18:06:35 -0400] [33412] [ERROR] Connection in use: ('0.0.0.0', 5000)
6:06:35 PM web.1 |  [2022-03-07 18:06:35 -0400] [33412] [ERROR] Retrying in 1 second.

And so on and so on.

I suspect this has to do with my Procfile. And admittedly, I'm not too sure on how to set it up. I currently have in my Procfile:

web: gunicorn --pythonpath backend.feh backend.feh.wsgi --log-file - 
release: python backend.manage.py makemigrations - - no-input

And my directory structure is like:

runtime.txt
requirements.txt
Procfile
backend/
    |-- __init__.py
        api/
        feh/
            |-- __init__.py
                errorlog
                settings.py
                urls.py
                wsgi.py
        static/
        db.sqlite3
        manage.py
scraper.py

I'm positive my Procfile is the cause for this issue but I don't know how to go about debugging this. At the very least, the project runs fine on my venv. Thank you in advance!

Neither of the processes in your Procfile is specified correctly.

  • The web command's --pythonpath should just be backend and it should receive the dotted path feh.wsgi as an argument:

    web: gunicorn --pythonpath backend feh.wsgi --log-file -

  • The release command refers to a file called backend.manage.py:

    release: python backend.manage.py makemigrations - - no-input

    That argument should be a path to a file, not a dotted Python module, and - - no-input should be the single argument --no-input. Try this instead:

    release: python backend/manage.py makemigrations --no-input

  • Thank you. But... now I'm getting an error where it says it can't find my feh/ folder. ``` text upon text of logs... 2022-03-08T02:24:28.926500+00:00 app[web.1]: ModuleNotFoundError: No module named 'feh'``` I suppose this might be for another question then. Thank you. – Domini Mar 08 '22 at 02:29
  • Okay, figured out my other error: Taken from [here](https://stackoverflow.com/questions/49457037/heroku-cant-find-my-settings-py-file), My web line in my Procfile should have been: `web: gunicorn --pythonpath backend feh.wsgi --log-file - ` Since Django isn't at the root of my project, I have specify django project directory. I knew my Procfile was the source of all my problems, THANK YOU CHRIS!!! – Domini Mar 08 '22 at 03:09
  • @Domini, you're right, I missed that. Thanks for pointing it out. I've updated my answer accordingly in case it helps others. – ChrisGPT was on strike Mar 08 '22 at 12:10
