Issue deploying Flask app to Heroku

Question

I want to update an app i have on heroku from a project i worked on over a month ago.

I just want to push my new .py app to it. But i get the following error when using git push heroku master

remote: -----> Failed to detect app matching https://codon-buildpacks.s3.amazonaws.com/buildpacks/heroku/python.tgz buildpack

My file structure is:

Procfile is web: gunicorn app:app

As far as im aware, having a current require.emts.txt and pushing should be all i need?

How can i trouble shoot this?

Here is the terminal print:

我通过执行git commit $ git commit -am "descrip"解决此问题，然后再执行git push $ git push heroku master ，只是执行git push导致与文件识别冲突
