Django version 2.2, using settings yaradish.settings
Starting development server at http://127.0.0.1:8000/
Quit the server with CTRL-BREAK.
Exception in thread Thread-1:
Traceback (most recent call last):

    hostname, aliases, ipaddrs = gethostbyaddr(name)
UnicodeDecodeError: utf-8 codec cant decode byte 0xd1 in position 0: invalid continuation byte

原因及解决方案:

一般来说编码错误是由中文引起的。从 traceback 最后一栈落在 gethostbyaddr 上可以看出:你电脑的主机名多半是设成了中文了。然后查看了自己的主机名,确实为中文

修改计算机主机名为英文

查看主机名

计算机右键属性,点击高级系统设置,图中标记即为主机名,修改如箭头步骤所示。修改后要重启电脑。
