cmd UnicodeDecodeError: 'utf-8' codec can't decode byte 0xb9 in position 77: invalid start byte

这个错误提示是UnicodeDecodeError: 'utf-8' codec can't decode byte 0xb9 in position 77: invalid start byte。根据引用和引用的信息，这个错误通常发生在编码错误的情况下。Python3默认使用utf-8编码，如果遇到中文字符，可能会出现解码错误。根据引用的信息，可以确认问题出现在获取主机地址的函数gethostbyaddr()上，其中传入的参数name是主机名，也就是电脑名。如果电脑名包含非utf-8编码的字符，就会导致解码错误。解决这个问题的方法是将电脑名改成英文名。通过测试，发现将电脑名改成英文后，问题就可以顺利解决。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
