Mac安装gunicorn成功，却无系统命令

python小白一枚，自己独立用Django开发个demo，在部署时用pip安装gunicorn后发现系统一直找不到命令

# gunicorn-bash: gunicorn: command not found

一开始上网搜了下，发现没啥人说
用witch找不到命令位置，就猜测是环境变量原因，查看自己mac上gunicorn安装路径：/usr/local/Cellar/python/2.7.14/Frameworks/Python.framework/Versions/2.7/bin/gunicorn
只能自己添加个环境变量啦，在/etc/bashrc下添加

PATH=$PATH:/usr/local/Cellar/python/2.7.14/Frameworks/Python.framework/Versions/2.7/bin/

$ which gunicorn
/usr/local/Cellar/python/2.7.14/Frameworks/Python.framework/Versions/2.7/bin//gunicorn
