当我尝试使用iPython的自动完成时，会话崩溃并出现以下错误:

如何修复这些错误?
尝试安装旧的jedi版本:
pip install --upgrade 'jedi<0.18.0'
这个bug有一个问题https://github.com/ipython/ipython/issues/12740
在pip安装ipython==7.19.0时遇到了同样的问题，幸运的是它在我的另一个羡慕器中工作，受到kuter的回答的鼓舞，我检查了jedi版本，确实有一个版本更改。
如果选择的答案不适合你，你可以安装这个特定的版本:
pip install jedi==0.17.2
我设法通过卸载python3, pip和ipython使错误消失。然后安装Anaconda。
我知道这不是一个解决方案，但它确实为我工作。
