Question

当我尝试在本地计算机上运行python程序时，遇到此错误：

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

    ) from err

在线上也有类似的帖子，我尝试了每个帖子的建议解决方案，但是没有一个可以解决我的错误。

这是我的设置内容。py

我之前曾发布过类似的帖子，但是现在没有人正在查看该帖子，因此在这里我创建了另一篇帖子，看看是否有人可以提供帮助。任何帮助或建议，表示赞赏。

好吧，我终于在网上找到了解决方案：首先要做的是：pip卸载whitenoise 然后做：pip安装“ whitenoise <4”

还要感谢所有在此帖子上发表建议的人。
