Kernel 笔记本中的错误 Jupyter 在 Anaconda 2019.03 为了 Python 3.7 在 macOS

我刚安装过 Anaconda 2019.03 为了 macOS 从 Python 3.7 我想用它来编程 Python 3 使用笔记本电脑 Jupyter. 当我跑步时 Jupyter Notebook, 没有什么作用，因为错误 Kernel.

我删掉了 Anaconda 为了 Python 2.7 和 Python 3.7 重新安装之前 /由于单独的问题，我删除并重新安装/, 我认为一些重要的文件 kernel, 我手动删除时可能已被删除 Anaconda. 我认为下面的错误消息显示了 Anaconda 从名为的文件夹开始

anaconda3

里面 root /

/

/, 但在错误消息的最后一行中，它似乎正在寻找我的主文件夹中的东西。 /

myhomefolder

/. 我不太确定如何解释，因为我是新手。
