  • Based on this : https://stackoverflow.com/a/51992855/8375783 you may have multiple python versions installed and one of them has the dependencies and you are running the other one. – Trapli Sep 04 '19 at 10:17
  • Do you also have a `Pipfile`? – ChrisGPT was on strike Sep 04 '19 at 11:58

I referred to this instructions and added the Pipfile follow: this:https://hackersandslackers.com/starting-a-python-web-app-with-heroku/. However,there was an trouble with python version when I try to deploy vitural python version in my desktop to heroku server which my not support flask_wtf.

BTW, to resolve this, I only add the Profile and requiments.txt file in my project .Then heroku will only add specific modules with python version of its server.

This is my struct folder: static

-templates

-app.py

-requirements.txt
