python - django 项目给出 500 内部服务器错误

问题描述

我有一个 Django 项目，它直到昨晚都运行良好。现在我收到了这个错误

这就是我在终端中得到的

我所做的只是尝试更改我virtualenv删除的最后一个virtualenv，因为它正在我的全局环境中安装包并创建一个新包，重新安装 requirements.txt，然后运行manage.py runserver. 现在我收到了这个错误。我不知道出了什么问题。

我正在使用 Windows10、Python3.6 和 Django 3.0

这是在 settings.py 中设置 DEBUG=TRUE 后的错误

这是我的终端中的错误，我猜 python 本身而不是 Django 有问题，如果有帮助的话

Django version 3.0, using settings 'configurations.settings'
