homebrew pip install jupyter error: ImportError: E

问题:

The end goal is to get jupyter notebook working on Mac OSX. Due to some conflicts with mac system python, I went the homebrew route:

brew install python

After homebrew is done installing python (and pip2)

export PATH=/usr/local/bin:/usr/local/sbin:$PATH is added to ~/.zshrc

source ~/.zshrc

Now running pip or pip2 gives the following error:

pip2 install jupyter

Traceback (most recent call last):
  File "/usr/local/bin/pip2", line 11, in <module>
