我可以打开jupyter笔记本，但我不能在Mac上运行包含python脚本的笔记本

我已经在python中使用jupyter和Atom一年多了。我目前正在macOS 10.14上使用Python 3.7.2。从终端运行Python没有问题，下面是我在运行

sys.PATH

后得到的路径：

['', '/Library/Frameworks/Python.framework/Versions/3.7/lib/python37.zip', '/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7', '/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/lib-dynload', '/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages']

我可以在jupyter中打开一个jupyter笔记本，但由于一些模糊的原因，我无法运行该笔记本，并且在页面右上角有一个红色的

内核错误

，当我单击它时，会显示以下错误消息：

这是我的路径（在命令：

nano~/.bash\u profile

之后获得）

我已经卸载了我计算机上的所有python安装，包括anaconda版本（python 2.7除外，因为我的mac不接受我删除它）

好的，我卸载了python，并用

自制重新安装了所有东西，它工作了
