Hosting discord bot through Heroku – deploy error

I am trying to host my discord bot through heroku. I’m coding with python. But I got the following error when deploying from GitHub:

-----> Using buildpack: heroku/python
-----> Python app detected
-----> No Python version was specified. Using the buildpack default: python-3.9.6
       To use a different version, see: https://devcenter.heroku.com/articles/python-runtimes

       ERROR: Command errored out with exit status 1: git checkout -q rewrite Check the logs for full command output.

That was the full build log that I saw on heroku. Can anyone help? Thx

Answer

You should change the first line in requirements.txt to git+https://github.com/Rapptz/discord.py. Because there is no tag or branch named “rewrite”.
