Я закомментировал свой проект и отправил по
git push heroku master
Но я получаю ошибку

Что я сделал не так?

Answer 1

[cython]

Heroku не смог определить язык, который использует ваш проект. Чтоб сделать это вручную перейдите из dashboard проекта в раздел Settings, в пунтке Buildpacks нажмите Add buildpack и выберите python

fantom_ask, смотрите на сообщение, которое вам выдаёт. Там написано, что buildpack, который нашёл heroku из runtime не совместим с вашим приложением. Попробуйте в Settings найти нужный buildpack, и указать его в runtime

[fantom_ask]

cython,
Я уже устанавливал как в документаций
python-3.7.4
python-3.7.8
python-3.6.1
https://elements.heroku.com/buildpacks/heroku/hero...
но результат тот же
