python3.7——History文件報錯

windows電腦

輸入CMD命令提示符

C:\Users\liuya>python
Python 3.7.0 (v3.7.0:1bf9cc5093, Jun 27 2018, 04:59:51) [MSC v.1914 64 bit (AMD64)] on win32

Failed calling sys.__interactivehook__
Traceback (most recent call last):
File "C:\Python\Python37\lib\site.py", line 439, in register_readline
readline.read_history_file(history)
File "C:\Python\Python37\lib\site-packages\pyreadline\rlmain.py", line 165, in read_history_file
self.mode._history.read_history_file(filename)
File "C:\Python\Python37\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 0x80 in position 247: illegal multibyte sequence

解決方法：

打開：C:\Python\Python37\lib\site-packages\pyreadline\lineeditor目錄下history.py文件，這個文件中包含了中文。

把報錯的history.py文件82行改一下，加一個encoding='utf-8'，最終顯示：for line in open(filename, 'r',encoding='utf-8'):

修改後記得保存

 

2、再次在cmd命令行界面，輸入python命令，查看顯示結果：

至此問題即解決

 

方法2：

刪除site-packages目錄的pyreadline文件夾

提示：readline模塊，有自動補全的功能
