解决terminal运行python时，UnicodeDecodeError: 'gbk' codec can't decode byte 0x80 in position 234: illegal multibyte sequence报错问题
问题描述
今天偶然在pycharm的terminal运行python时发现有如下警告问题。
Python 3.8.12 (default, Oct 12 2021, 03:01:40) [MSC v.1916 64 bit (AMD64)] :: Anaconda, Inc. on win32

UnicodeDecodeError: 'gbk' codec can't decode byte 0x80 in position 234: illegal multibyte sequence
解决方法
打开Anaconda的安装路径，如C:\Users\15619\anaconda3\Lib\site-packages\pyreadline\lineeditor中的history.py文件，找到第82行位置的如下代码：for line in open(filename, 'r'):
替换为如下：
for line in open(filename, 'r', encoding='utf-8'):
