MacOS更新弄乱了我的Jupiter安装

如何解决MacOS更新弄乱了我的Jupiter安装

运行操作系统更新后，我遇到了MacOS的麻烦。现在Jupiter笔记本电脑根本无法工作。

我卸载了Anaconda，干净的系统，但笔记本无法正常工作。

$ python3 -V

Python 3.8.5


pip --version
-bash: /usr/local/bin/pip: /usr/local/opt/python/bin/python3.7: bad interpreter: No such file or directory

启动笔记本

$ jupyter notebook

在Jupyter笔记本中，出现内核错误，如附件中的图像所示。

当我单击内核按钮时，出现以下错误消息：

现在我不能工作，什么都没有。对这个解决方案有什么想法吗？
