Python django:获取错误属性error:'；非类型'；对象没有属性'；拆分'；即使我能够访问该页面

运行命令时出现以下错误。不过，页面正在打开，但在下面的命令提示下出现错误。我参考了其他stackflow页面，其中也有类似的错误，但没有帮助

python manage.py runserver

错误：

任何想法，我应该在哪里调查。如果您需要任何特定文件，请告诉我。

这意味着

self.status

以某种方式返回一个None值。因此，请插入一张支票，然后像这样尝试：

if self.status != None:
    self.status.split(' ',1)[0]

您应该通过谷歌搜索的主要错误是

ConnectionAbortedError:[WinError 10053]主机中的软件中止了已建立的连接

您可以从这里开始：@MKaras上面的链接没有解决问题。我使用的是Python3.7.2。在哪个文件中以及它将解决什么问题。split只生成给定字符串的列表。它无法创建非类型对象的列表。因此，只需将您的行替换为上面提到的行，因为它至少会检查您的对象是否不存在None@KKimash你可能想学习和阅读回溯。这个错误出现在wsgiref\simple_server.py（Python的stdlib代码）中，实际上这只是另一个问题的结果。@brunodesshuilliers明白了！因为回溯指向标准文件权限（与Django一起预装），所以可以认为这是另一个问题的结果吗？如果它指向用户自己创建的文件，那么我们会更改代码本身吗？
