I try to deploy a Django app to Heroku and the push get rejected. The result shows that : Push rejected, failed to compile Python app. From the error script, it seems that the model "ConfigParser' is not found.

I google this problem and it seems that the other guy also have this problem (https://github.com/hashedin/squealy/issues/229). Is it true that Python 3.7 could not work in Heroku? How could I deal with it? Some part of the detailed command result scripts are as followed:

Any chance this could be a python3 import error on the import for the module ConfigParser?

I hope this helps.

This is Abe Karplus's answer:

In Python 3, ConfigParser has been renamed to configparser for PEP 8 compliance. It looks like the package you are installing does not support Python 3.

Thx. So how could I do to deal with it?
I think the simplest thing to do would be pip install configparser and remove the former ConfigParser from requirements by pip uninstall ConfigParser && pip freeze > requirements.txt. Try and see if this works
It's still not working when I push to heroku. Should I make some change based on the following stricpt? remote: File "/tmp/pip-build-t_7e9for/MySQL-python/setup_posix.py", line 2, in <module> remote: from ConfigParser import SafeConfigParser remote: ModuleNotFoundError: No module named 'ConfigParser'
Should I delete the MySQL-python instead? like pip uninstall MySQL-python?
actually, try one of these pip install configparser or pip3 install configparser if those don't work try pip install ConfigParser or pip3 install ConfigParser. Also, if you think my answer to be sufficient please select it as the best answer.
