在 django 中运行服务器后，我收到 KeyError: 'django'

Question

我对 Django 不太熟悉，已经做了 3 个多月了，但我从未见过这样的错误。如果有人可以帮助我摆脱这种情况，请。

我正在做short_url模块，bt之前我已经pip安装了shorturls，然后我创建了一个应用程序shorturls。再次，我必须删除应用程序的短网址。从那以后我就一直面临这个问题。

以下是我对错误的完整回溯：

Traceback (most recent call last):
  File "C:\Users\user\AppData\Local\Programs\Python\Python39\lib\site-packages\django\template\utils.py", line 66, in __getitem__
    return self._engines[alias]
KeyError: 'django'

During handling of the above exception, another exception occurred:
