如何指示Jupyter使用python2而不是python3

Question

給定一個PYTHONPATH ，它似乎指向python ：

cat $(which jupyter)

#!/bin/bash
JUPYTER_PATH="/usr/local/etc/jupyter" 

PYTHONPATH="/usr/local/Cellar/jupyter/1.0.0_1/libexec/lib/python2.7/site-packages:
/usr/local/Cellar/jupyter/1.0.0_1/libexec/vendor/lib/python2.7/site-packages:
/usr/local/lib/python2.7/site-packages" 
exec "/usr/local/Cellar/jupyter/1.0.0_1/libexec/bin/jupyter" "$@"

那為什么jupyter notebook報告python3？
