casperjs安装与遇到的问题

1. 安装PhantomJS(CasperJS 依赖于PhantomJS >= 1.3)

解压安装:https://code.google.com/archive/p/phantomjs/wikis/Installation.wiki
文件解压到~目录下,配置环境变量:
export PATH="$PATH:/Users/yujiaxi/phantomjs-2.1.1-macosx/bin"
查看是否安装成功:phantomjs —version 输出2.1.1

2. 安装casperjs:

git clone git://github.com/n1k0/casperjs.git
cd casperjs
git checkout tags/0.6.9
ln -sf `pwd`/bin/casperjs /usr/local/bin/casperjs

查看是否安装成功:casperjs —version
并没有返回版本号,返回信息:CasperJS needs at least PhantomJS v1.5.0
但是我的phantomjs是2.x?

找到/Users/yujiaxi/casperjs/bin/bootstrap.js 文件,
把红框里的这些:
if (phantom.version.major !== 1 || phantom.version.minor < 5) {
    console.error('CasperJS needs at least PhantomJS v1.5.0');
    phantom.exit(1);
}

替换成:

var system = require('system');
var argsdeprecated = system.args;
argsdeprecated.shift();
phantom.args = argsdeprecated;


(function (version) {
       // required version check
       if (version.major === 1) {
           if (version.minor < 8) {
               return __die('CasperJS needs at least PhantomJS v1.8 or later.');
           }
           if (version.minor === 8 && version.patch < 1) {
               return __die('CasperJS needs at least PhantomJS v1.8.1 or later.');
           }
       } else if (version.major === 2) {
           console.log("Warning PhantomJS v2.0 not yet released. There will not be any official support for any bugs until stable version is released!");
       }
       else return __die('CasperJS needs PhantomJS v1.x or v2.x');
   })(phantom.version);

然后就可以
