python - 选项卡在Windows上的python anaconda repl中不起作用

Question

Python 3.5.4 |Anaconda, Inc.| (default, Nov  8 2017, 14:34:41) [MSC v.1900 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> def func():
... Readline internal error

    readline.redisplay()

这就是我在控制台中按tab键时得到的结果。空间还可以。这和水蟒有关，因为racket的repl工作正常。更新每个包都没有帮助。当我在文件中运行程序时，制表符起作用。在GIT BASH和CMD中都存在问题。

📋复制上次回溯文件路径C:\Users\Alex\Anaconda3\lib\rlcompleter.py
用任何文本编辑器打开
如果有VsCode，请使用cmd并复制此👇
code C:\Users\Alex\Anaconda3\lib\rlcompleter.py
👀看看回溯告诉我们的
如下图所示改变这些线路（开始line 80），它就会工作

...
if _readline_available:                     ## The old one is ##
    if hasattr(readline, 'redisplay'):      # if _readline_available:
        readline.insert_text('\t')          #     readline.insert_text('\t')
        readline.redisplay()                #     readline.redisplay()
    return ''                               # return ''
...

⚠不要忘记重新启动python终端
