为什么我全局安装了jade，还是不能用jade命令

Question

我先全局安装jade

taolinweideMacBook-Pro:practice_jade Vagor$ sudo npm install -g jade
Password:
/usr/local/Cellar/node/5.2.0/bin/jade -> /usr/local/Cellar/node/5.2.0/lib/node_modules/jade/bin/jade.js
/usr/local/Cellar/node/5.2.0/lib
└── jade@1.11.0 

之后还是不能用jade？为什么

taolinweideMacBook-Pro:practice_jade Vagor$ jade index.html

-bash: jade: command not found

Answer 1

因为不在PATH环境变量内，你是用brew安装的node，所以需要再手动链接到/usr/local/bin
