Python hitting tab fails with Python AttributeError: module 'readline' has no attribute 'redisplay'

Question

在 Windows 上使用 Python 3.7.3 (Anaconda)，点击选项卡会导致以下回溯：

Readline internal error
Traceback (most recent call last):
  File "C:\...\anaconda3\lib\site-packages\pyreadline\console\console.py", line 768, in hook_wrapper_23
    res = ensure_str(readline_hook(prompt))
  File "C:\...\anaconda3\lib\site-packages\pyreadline\rlmain.py", line 571, in readline
    self._readline_from_keyboard()
  File "C:\...\anaconda3\lib\site-packages\pyreadline\rlmain.py", line 536, in _readline_from_keyboard
    if self._readline_from_keyboard_poll():
  File "C:\...\anaconda3\lib\site-packages\pyreadline\rlmain.py", line 556, in _readline_from_keyboard_poll
    result = self.mode.process_keyevent(event.keyinfo)
  File "C:\...\anaconda3\lib\site-packages\pyreadline\modes\emacs.py", line 243, in process_keyevent
    r = self.process_keyevent_queue[-1](keyinfo)
  File "C:\...\anaconda3\lib\site-packages\pyreadline\modes\emacs.py", line 286, in _process_keyevent
    r = dispatch_func(keyinfo)
  File "C:\...\anaconda3\lib\site-packages\pyreadline\modes\basemode.py", line 257, in complete
    completions = self._get_completions()
  File "C:\...\anaconda3\lib\site-packages\pyreadline\modes\basemode.py", line 200, in _get_completions
    r = self.completer(ensure_unicode(text), i)
  File "C:\...\anaconda3\lib\rlcompleter.py", line 80, in complete
    readline.redisplay()
AttributeError: module 'readline' has no attribute 'redisplay'

环境详情：

Windows 10 个 64 位
Python 3.7.3、Anaconda 分布
pyreadline == 2.1
Tab 键在 IPython

我知道 pyreadline 可能会导致此问题。 Tab not working in python 3.6, working in 3.5, 3.6 32 bit version on Windows 建议卸载 pyreadline。但是，当我尝试 pip uninstall pyreadline 时出现此错误：

Cannot uninstall 'pyreadline'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.

尝试这个也没有帮助：Unable to install 'pyreadline' using pip on Windows

Anaconda 模块 readline 与标准 Python readline 不同，后者具有重新显示方法。我发现使这项工作可行的解决方法是禁用自动完成功能。要存档，您需要在文件 rlmain.py 行 58.[=13 中将属性 disable_readline 设置为 True =]

..\Anaconda3\Lib\site-packages\pyreadline\rlmain.py

class BaseReadline(object):
    def __init__(self):
        self.allow_ctrl_c = False
        self.ctrl_c_tap_time_interval = 0.3

        self.debug = False
        self.bell_style = 'none'
        self.mark = -1
        self.console=MockConsole()
        self.disable_readline = True # Old value: False
