UnicodeDecodeError: 'gbk' codec can't decode byte 0xaf in position 341

错误

Python 3.8.2 (tags/v3.8.2:7b3ab59, Feb 25 2020, 23:03:10) [MSC v.1916 64 bit (AMD64)] on win32     Type "help", "copyright", "credits" or "license" for more information.

解决办法

进入到该目录：C:\Users\向成功\AppData\Local\Programs\Python\Python38\Lib\site-packages\pyreadline\lineeditor ，     history.py文件的第82行，修改如下：     for line in open(filename, 'r',encoding='utf-8'):     在原有的open函数里 新增了一个参数选项encoding='utf-8'      就可以解决了
