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. Failed calling sys.__interactivehook__ Traceback (most recent call last): File "C:\Users\向成功\AppData\Local\Programs\Python\Python38\lib\site.py", line 440, in register_readline readline.read_history_file(history) File "C:\Users\向成功\AppData\Local\Programs\Python\Python38\lib\site-packages\pyreadline\rlmain.py", line 165, in read_history_file self.mode._history.read_history_file(filename) File "C:\Users\向成功\AppData\Local\Programs\Python\Python38\lib\site-packages\pyreadline\lineeditor\history.py", line 82, in read_history_file for line in open(filename, 'r'): 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\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
