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

Im deploying a Django 2.2.1 Project in Heroku but I had this error:

-----> Python app detected
! Requested runtime (Python 3.7.3) is not available for this stack (heroku-18).
! Aborting. More info: https://devcenter.heroku.com/articles/python-support
! Push rejected, failed to compile Python app.
! Push failed

I tried asking a question on SO but it got closed.

Anyone familiar with this?

Have you contacted support? They are not super quick to respond if you're on the free tier.

What does your runtime.txt file contain?

is it "python-3.7.3" or "Python-3.7.3"? Heroku says the name is case sensitive: devcenter.heroku.com/articles/pyth...

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.
