After the second time deploying the Django app to Pythonanywhere, (I re-edited and overwritten in VS code and did git push) I got the following error.
WARNING: Package(s) not found: django

The command is
$ pa_autoconfigure_django.py https://github.com/[user_name]/[project_name].git --nuke
The first deployment succeeded but the second one is not. I don't know the cause and how to overwrite it...
