当我尝试运行我的 python 程序时，我遇到了一个 Django 导入模块错误

Question

当我尝试在本地机器上运行 python 程序时，我遇到了这个错误：

Traceback (most recent call last):
  File "C:\Users\Thomas\AppData\Local\Programs\Python\Python37\lib\threading.py", line 917, in _bootstrap_inner
    self.run()

    ) from err
django.core.exceptions.ImproperlyConfigured: WSGI application 'mysite.wsgi.application' could not be loaded; Error importing module.

网上也有类似的帖子，我尝试了每个帖子中建议的解决方案，但没有一个可以解决我的错误。

这是我的setting.py的内容

我之前发布过类似的帖子，但没有人再查看该帖子，所以我在这里创建了另一个帖子，看看是否有人可以提供帮助。任何帮助或建议表示赞赏。

好的，我终于在网上找到了解决方案： 第一步：pip卸载whitenoise 然后执行： pip install "whitenoise

另外，感谢所有在这篇文章中提出建议的人。
