У меня есть приложение Django, которое я пытаюсь развернуть в GCP. Приложение отлично работает, когда я запускаю его локально, и оно без проблем развертывается в GCP (через развертывание приложения gcloud). Когда я открываю веб-страницу, я получаю эту ошибку «502 Bad Gateway 502 nginx» из-за «ошибки ModuleNotFoundError: нет модуля с именем «google»». Я не смог найти, как правильно импортировать Google в мое приложение GCP. Подробнее ниже, любая помощь приветствуется.

Вот проанализированная трассировка стека (через отладчик GCP):

Я не смог найти, как правильно импортировать Google в мое приложение GCP, какие-либо советы?

Зависимости для приложений Python могут быть объявлены в стандартном requirements.txt файле.
Создайте requirements.txt в корне вашего каталога исходного кода, чтобы перечислить все зависимости модулей, которые требуются вашему приложению (модуль Google — единственный, который необходим в этом примере):

 google-api-python-client
  

При развертывании в App Engine зависимости, указанные в requirements.txt файле, будут автоматически установлены с вашим развернутым приложением. Вы можете использовать любой Linux-совместимый пакет Python, включая пакеты, для которых требуются собственные расширения C.
