Я публикую это, чтобы надеяться помочь кому-то еще с той же проблемой. Я использовал документацию GCP для развертывания моего приложения на Python в GCP App Engine. При выходе из системы произошла следующая ошибка:

Мне потребовалось немного времени, чтобы отследить проблему, но logilab-astng относится к pylint и мой файл needs.txt содержал
django-lint==2.0.4
после удаления этого развертывание сработало.
Если вам нужен django-lint, то, честно говоря, я не знаю решения.
