烧瓶UnicodeDecodeError:'utf-8'编解码器无法解码位置0的字节0xb3:无效的起始字节 [英] flask UnicodeDecodeError: 'utf-8' codec can't decode byte 0xb3 in position 0: invalid start byte

问题描述

我正在学习烧瓶模块我复制了代码，但没有用，并给了我UnicodeDecodeError

感谢您的帮助

解决方案

正如回溯指出的那样，您计算机的主机名具有非ASCII字符.正如

I'm learning the flask module I copy the code but it didn't work and give my the UnicodeDecodeError

Thanks for your help

解决方案

As the traceback point out, your computer's hostname has non-ASCII character. As this document said, you can use this way to get your hostname:

$ python
>>> from socket import *
>>> getnameinfo(("127.0.0.1", 0), 0)
('user-greyli', '0')  # here the 'user-greyli' is hostname

In windows system, the hostname was same as computer's name. So, you need to rename your computer's name.

How to do it? Just check this page. Besides, as a bonus, I capture a picture in Chinese that includes all the operation you need :)
