При отправке моего приложения Django в Heroku, я получаю это предупреждение
remote: -----> Python app detected
remote: ! The latest version of Python 3 is python-3.6.5 (you are using python-3.6.4, which is unsupported).
remote: ! We recommend upgrading by specifying the latest version (python-3.6.5).
remote: Learn More: https://devcenter.heroku.com/articles/python-runtimes
Но я получаю сообщение об ошибке при попытке обновить версию Python.В моем локальном окружении это уже Python 3.6.5, поэтому я просто обновляю свой runtime.txt файл, переключающий python-3.6.4 на python-3.6.5.
Однако, это вызывает ошибку при нажатии приложения.Как ни странно, ошибка не всегда одинакова.
Один пример:

Я видел похожие вопросы, такие как этот , но ошибка обычно связана со статической папкой, что не в моем случае.
Примечания
Если я нажимаю на приложение без обновления доpython 3.6.5 ошибка не возникает.
Я недавно заменил свой старый MacBook на новый.Поскольку все работает нормально, если я не пытаюсь обновить версию Python, я думаю, это не имеет ничего общего, но на всякий случай я подумал, что стоит упомянуть.
Любая идеяпочему это происходит и как я могу решить это?
