安装yslowjs

基于这篇文章：http://blog.csdn.net/qdujunjie/article/details/46806441

安装完nodejs和npm之后，我们来安装yslowjs。

参考这篇文章：http://mervine.net/projects/npms/yslowjs

sudo npm install yslowjs
           

安装成功：

[wz@supportserver- node-v0]$ sudo npm install yslowjs

yslow.js is installed.
=> /usr/local/nodejs/node-v0/node_modules/yslowjs/lib/yslow_phantom.js

You can reference it within node like so:

  var YSlow = require('yslow');
  var yslow = new YSlow(url, args);
  console.log(yslow.yslowjs);
