Node.js如何使用phaeromjs的cheerio

Question

我试过了：

    phantom.casperPath = '/Volumes/SSD/admin/Desktop/parser/node_modules/casperjs';
    phantom.injectJs('/Volumes/SSD/admin/Desktop/parser/node_modules/casperjs/bin/bootstrap.js');

    var cheerio = require('cheerio');
    var casper = require('casper').create(); 
    casper.start('http://google.com', function() {

     $ = cheerio.load(document.querySelector("body").innerHTML);
     console.log($('.logo-subtext'));

   });

脚本显示错误：脚本显示错误
