re: Requested runtime (Python 3.7.3) is not available for this stack (heroku-18). VIEW POST


any solution? having the same problem but am using flask


Do you mind posting your Procfile? If I'm not mistaken, it should be

web: gunicorn app_name:app --log-file -

Don't forget to replace the name of your app on app_name.

Also don't forget to freeze your requirements

pip freeze > requirements.txt

You can check this video. It teaches you 5 ways to deploy a python web app.


Thanks for your assistance bro. The problem was the requirements were not complete.
