无法在Django TCP/IP连接上运行服务器？

Question

我已经从django、whitenoise等下载了所有软件包，错误还在继续。
cmd与env和triyng一起运行，以推动我仍然处于相同的错误中

我正在尝试使用本地主机运行我的服务器，结果：

The above exception was the direct cause of the following exception:

你能给我们一些更详细的信息吗，比如你正在运行什么命令来启动你的服务器，你是想从同一台计算机上查看网页还是想远程连接到它

您是否尝试过使用此python manage.py runserver运行服务器，然后尝试连接到它

您使用端口5432是否有任何原因，因为默认值为8000，所以最好在更改端口之前先使其工作
