这是我在 Stack Overflow 上的第一个问题。我已经学习了大约一个月的 Python 和两周的 Django。我尝试在我的 MacBook Pro 上运行第二台服务器,然后遇到了这些问题。(下面来自我的终端的错误消息)第二台服务器包括其他一些应用程序,包括 Pihole。我删除了第二个服务器文件并重新启动,问题解决了!接下来是我尝试在 Django 中编辑我的 Views.py 文件,然后当我在虚拟环境文件夹中重新启动我的 Django 服务器时,同样的错误消息又出现了。请参阅以下错误:

这是我在 Stack Overflow 上的第一个问题,我现在非常不确定我是否能让我的服务器在我的 MacBook Pro 上再次运行 Python 3.9.0 和 Django 3.1.3 这是我上面遇到的错误,我可以' t 连接到 127.0.0.1 ,我的 MacBook Pro 上的本地主机。请尝试给我一个关于如何进行的线索。我一直在学习 djangobook.com 的课程。

另外,我的 Django 安装是否存在路径问题?我在正确更新为使用 Python 3.9 的 MacBook Pro 上运行。我认为这可能与这部分错误有关:
"/Library/Frameworks/Python.framework/Versions/3.9/lib/python3.9/site-packages/django/core/management/__init__.py", line 401, in execute_from_command_line
utility.execute()
这看起来合理吗?settings.py 中的标记代码出现在第 123 行。在我看来,python 3.9 有一个包含的 django 安装,它通过路径与 mfdw_project 文件混淆。我是对的,我应该怎么做?
