解决方案
web:gunicorn app:app 是标准的 Procfile.它期望您的 .py 文件应命名为 app.py.
如果您想更改 .py 名称，您也应该更改 Procfile.web:gunicorn my_app_name:app之后你可以命名你的文件 - my_app_name.py
I'm trying to deploy a Flask app to Heroku. After deploying, application crashes and I get an error ModuleNotFoundError: No module named 'app'.

what's wrong with this, How can I successfully deploy an app??
解决方案
web:gunicorn app:app is standard Procfile. It expects that your .py file should be named app.py.
If you want to change .py name you should change Procfile as well.web:gunicorn my_app_name:appAfter that you can name your file - my_app_name.py
