There is requirements.txt

pyTelegramBotAPI==3.6.6
telegram==0.0.1

There is a runtime.txt
"python-3.7.0"
Launched heroku buildpacks:set heroku/python
I also completely deleted the bot and made 1 button "ala check" mb swears because of the libraries, but nothing happened.
I used Pyton 3.7.2, then I started using Python 3.7.0, nothing helps, I don’t know what else I can think of ((((

Answer 1

In the runtime.txt file, specify " python-3.7.0 " without the quotes.
