Python之Dijango的“坑” hostname, aliases, ipaddrs = gethostbyaddr(name) UnicodeDecodeError: 'utf-8' cod

错误代码提示:

hostname, aliases, ipaddrs = gethostbyaddr(name)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xcc in position 0: invalid continuation byte

在命令行输入 python manage.py runserver启动服务器的时候，突然出现下面的错误

Traceback (most recent call last):
  File "learning.py", line 106, in <module>
    main()
  File "learning.py", line 37, in main

 分析  ：重点是最后一句红色的话，从中我们可以看出，是要得要你自己电脑的主机名，但是现在的主机名是中文，所以导致编码出现错误

    解决方案：把你自己电脑的主机名改成英文的，不要写中文，然后重启电脑就可以了

注：你可以在python中的socket.py 中来看一下出错的地方
