解决方法
安装phantomjs

一、下载
http://download.csdn.net/download/fengsen0515/10035568

二、解压
tar -xjvf phantomjs-2.1.1-linux-x86_64.tar.bz2
（如果解压报错，需要安装bz2：yum install bz2）

三、创建链接
ln -s /apps/phantomjs/phantomjs-2.1.1-linux-x86_64/bin/phantomjs /usr/bin
（PS：/apps/phantomjs/phantomjs-2.1.1-linux-x86_64/bin/phantomjs是绝对地址）

四、测试
phantomjs –version
