如果我将我的 Django 项目部署到 Heroku，我会得到 ModuleNotFoundError: No module named 'django'。有谁知道这是为什么？

您正在安装 django-heroku==0.0.0 这是您真正想要的吗？
我已经向 Heroku 部署了 5 个以上的项目，我从来没有遇到过这样的错误，但是从错误消息中可以明显看出 Django 可能没有安装，重新部署你的项目，看看它是否有效
我现在能够解决问题了。这是因为我没有创建生产部署所需的 static_root 和 staticfiles_storage 文件夹
如果我将我的 Django 项目部署到 Heroku，我会得到 ModuleNotFoundError: No module named 'django'。有谁知道这是为什么？
