收到“严重错误”以重新安装Anaconda

问题描述

与许多人一样，升级到MacOS Catalina之后，我重新安装了Anaconda。我没有“卸载”而是删除了文件夹（我不是超级用户，但偶尔还是python用户）。

我全新安装了Anaconda 3，并将python更新为Python 3.8。当启动笔记本时，出现错误消息“内核错误”。

单击“内核错误”按钮，我看到以下消息：

FileNotFoundError: [Errno 2] No such file or directory: '/anaconda2/envs/snakes/bin/python3'

但是当我在终端中键入“ python”时，我看到安装了python 3.8：

谁能帮助我更好地理解这一点？在此期间，我是否有冒着这个新的anaconda安装与初始安装之间混淆的风险？
