python - Jupyter 笔记本，错误的 sys.path 和 sys.executable

Question

我正在尝试在 Jupyter Notebook 中运行 python 库的 anaconda 分发，但是当我运行笔记本时，我不断收到 ImportErrors，因为 python 路径设置为 Mac OS X 10.11 的默认分发

当我打印出 sys.path 和 sys.executable 时，它​​们在运行 python 和运行 jupyter notebook 时有所不同。例如，

from pprint import pprint as p
import sys

p(sys.path)

在 python 中执行此操作后，我得到了正确的输出:

['',

 '/Users/glennraskovich/anaconda2/lib/python2.7',
 '/Users/glennraskovich/anaconda2/lib/python2.7/plat-darwin',

 '/Users/glennraskovich/anaconda2/lib/python2.7/site-packages',
 '/Users/glennraskovich/anaconda2/lib/python2.7/site-packages/aeosa']

但是在 jupyter notebook 中运行时我得到:

对于 sys.executable，

p(sys.executable)

在 python 中，正确的输出:

/Users/glennraskovich/anaconda2/bin/python

但是在jupyter notebook中，sys.executable没有设置成anaconda版本

/usr/local/opt/python/bin/python2.7

我已经尝试在我的 .bashrc 和 .bash_profile 中设置 PATH，并使用 which python、which jupyter 等命令显示 anaconda 路径，但 jupyter notebook 没有使用 anaconda 路径。这可能是什么问题？

我找到了解决方案，因为内核设置为使用默认的 mac os x 的 python，我使用命令修复了它

python2 -m pip install ipykernel

python2 -m ipykernel 安装--用户
