在 Heroku 上部署 Django 項目：ModuleNotFoundError

Question

我沒有在我的項目中導入用戶。 項目的每個方面都在本地運行。 我正在為我的項目使用 Visual Studio。

在我的項目目錄中

Settings.py INSTALLED_APPS =

# Add your apps here to enable them
'users.apps.usersConfig',
'resume.apps.resumeConfig',
'MainApp.apps.MainAppConfig',
'crispy_forms',
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',

簡介：

web: gunicorn Project.Project.wsgi:application

這是錯誤

Answer 1

我認為導入錯誤的原因是INSTALLED_APPS列表中的users.apps.usersConfig條目（以及其余條目）將在運行時導入。 根據 Heroku 的 文檔，您的問題可能是 Procfile 的語法。 也許嘗試以下方法：

web: gunicorn Project.wsgi
