执行sudo npm install -g jgb-cli 时报错
执行以下命令：
sudo chown -R liuqian /usr/local/lib/node_modules/
然后 npm install -g jgb-cli 成功
Mac新用户，对权限这块还是不太懂啊，虽然解决了，但是具体原理还需继续学习

Solution :-
You need to change ownership of node_modules, because you use sudo npm install -g node-sass so its ownership set to root,
To change ownership to current user as group -
sudo chown -R root:YOUR_USERNAME /usr/local/lib/node_modules/
sudo chmod -R 775 /usr/local/lib/node_modules/
