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

解决办法

进入到该目录：C:Users向成功AppDataLocalProgramsPythonPython38Libsite-packagespyreadlinelineeditor ，
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
