node.js v4.2.2 安装time模块是出错
gyp WARN EACCES user "root" does not have permission to access the dev dir "/home/countly/nodejs/lib/node_modules/time/.node-gyp/0.10.36"
gyp WARN EACCES attempting to reinstall using temporary dev dir "/home/countly/nodejs/lib/node_modules/time/.node-gyp"
百度了好久资料，终于发现了解决办法，特此记录
sudo npm install time -g --unsafe-perm
增加了--unsafe-perm
顺便写一下新颁布 express 的安装
npm -g install express
npm -g install express-generator
nodejs gyp WARN EACCES user "root" does not have permission to access the dev dir
