如何解决Ipython：自动完成使会话崩溃'sys' 未定义

当我尝试使用 iPython 的自动完成功能时，会话崩溃并显示以下错误：

If you SUSPECT this is an IPython 7.19.0 bug,please report it at:
    https://github.com/ipython/ipython/issues
or send an email to the mailing list at [e-mail]

You can print a more detailed traceback right Now with "%tb",or use "%debug"
to interactively debug it.

Extra-detailed tracebacks for bug-reporting purposes can be enabled via:
    %config Application.verbose_crash=True

如何修复这些错误？

解决方法

尝试安装旧的绝地版本：

pip install --upgrade 'jedi<0.18.0'

该错误 https://github.com/ipython/ipython/issues/12740

存在问题 ,

我通过卸载 python3、pip 和 ipython 设法使错误消失。然后安装 Anaconda。

我知道这不是解决方案，但它为我完成了工作。
