python - 我可以打开jupyter笔记本，但是无法在Mac上运行带有python脚本的笔记本

我已经将jupyter以及Atom与python一起使用了一年多了。我目前在macOS 10.14上使用Python 3.7.2。从终端运行Python没问题，这是运行sys.path之后获得的路径：

['', '/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jupyter笔记本，但是由于某些晦涩的原因，我无法运行该笔记本，并且单击该页面时，页面右上角有一个红色Kernel error并显示以下错误消息：

PermissionError: [Errno 13] Permission denied: '/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7'

这是我的路径（在命令后获取：nano ~/.bash_profile）

# Homebrew
export PATH=/usr/local/bin:$PATH

# Setting PATH for Python 3.7
# The original version is saved in .bash_profile.pysave
PATH="/Library/Frameworks/Python.framework/Versions/3.7/bin:${PATH}"
export PATH

# Setting PATH for Python 3.7
# The original version is saved in .bash_profile.pysave
PATH="/Library/Frameworks/Python.framework/Versions/3.7/bin:${PATH}"
export PATH

我已经卸载了计算机上的所有python安装，包括anaconda版本（python 2.7除外，因为我的Mac不接受我将其删除）

最佳答案

好的，我所做的是我卸载了python并使用Homebrew重新安装了所有内容，并且它正常工作
