如何指示jupyter使用python2而不是python3

Question

鉴于PYTHONPATH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" "$@"

那么为什么jupyter notebook会报告python3？
