当我使用node-horseman打开带有nodejs的phantomjs时,幻像进程就死了

Question

当我使用'node-horseman'来控制Node.js的phantomjs时,我遇到了一个问题:

Unhandled rejection HeadlessError: Phantom Process died
at ClientRequest. (/Users/zhuyingda/nodejs/veneno/node_modules/node-phantom-simple/node-phantom-simple.js:655:12)
at emitOne (events.js:77:13)
at ClientRequest.emit (events.js:169:7)
at Socket.socketOnEnd (_http_client.js:288:9)
at emitNone (events.js:72:20)

at endReadableNT (_stream_readable.js:905:12)
at doNTCallback2 (node.js:441:9)
at process._tickCallback (node.js:355:17)

我刚刚运行此代码:

var Horseman = require('node-horseman');
var horseman = new Horseman();
horseman
  .userAgent("Mozilla/5.2 (Windows NT 6.1; WOW64; rv:27.0) Gecko/20100101 Firefox/27.0")
  .on('resourceRequested', function (requestData, networkRequest) {
    if(!/[png|jpg|js|css]$/.test(requestData.url)){
      console.log(requestData.url);
    }
  })
.open('http://www.zhuyingda.com')
.log() // prints out the number of results
.close();

我确信我的网络很好,我可以在我的浏览器中连接这个网站,而且我也可以卷曲这个网址并获得回复.如果我打开查尔斯或其他VPN程序,问题将得到解决.我想知道为什么？
