Pu sh проект Heroku был отклонен, если я изменю Python версию

1 голос
/ 20 февраля 2020

У меня есть проект Python Scrapy на heroku с использованием Python 2. Я все еще могу добавить sh в Heroku, если у меня будет какое-то обновление кода.

Теперь я хочу обновить python версию на Python 3.

Похоже на поддержку Heroku Python 3: https://devcenter.heroku.com/changelog-items/1442

Поэтому я обновляю свой runtime.txt файл с python-2.7.15 до python-3.7.0

И мой requirements.txt: 

pymongo==3.5.1
Scrapy==1.4.0
scrapyd==1.0.1
scrapy-heroku==0.7.1
cffi==1.6.0
requests==2.5.3

А затем введите git push heroku master, вот информация терминала:

Если мой проект python версия по-прежнему 2.7.15 pu sh будет работать.

Я не знаю, почему я получаю отклонение при изменении на 3.7.0, как мне обновить мой проект до * 1040? * 3 на Heroku?

При изменении requests==2.23.0

Вы (косвенно) зависите от distribute, который является

устаревшим пакетом [предоставляющим] простой уровень совместимости, который устанавливает Setuptools 0.7 +

Он не строится должным образом из-за 

AttributeError: module 'importlib._bootstrap' has no attribute 'SourceFileLoader'

, что имеет смысл, поскольку importlib._bootstrap не содержит SourceFileLoader класс в Python 3.7.

* 1016 Страница PyPI *distribute сообщает, что она совместима с Python 2.4, 2.5, 2.6, 2.7, 3.1, 3.2 и 3.3.

Она загружается старой версией requests. Обновите requirements.txt, чтобы использовать более новую версию: последняя версия в настоящее время - 2.23.0 .

Всегда полезно попробовать установить в чистой локальной виртуальной среде с вашего requirements.txt чтобы убедиться, что у вас есть хорошая конфигурация после крупного обновления, и переход от Python 2.7 к Python 3.7 определенно считается серьезным обновлением.

Как только вы будете уверены в содержании вашего requirements.txt, зафиксируйте и повторно разверните.
