Question

我通过phantom包使用meteorhacks:npm npm包。但是当在Meteor.js下运行基本的Phantomjs示例时，我收到Cannot find 'webpage'错误。

为什么会这样？

代码

var phantomjs = Meteor.npmRequire('phantom')
var page = Npm.require('webpage').create();
page.open('http://github.com/', function() {
    console.log('Page Loaded');
    phantom.exit();
});

packages.json

{
    "phantom": "0.7.2"
}

网页是PhantomJS模块，而不是NPM包。 PhantomJS和node.js具有不同的运行时，这就是您需要使用像幻像包这样的桥的原因。 phantom本身将提供对page：

的引用

var phantom = Meteor.npmRequire('phantom')
phantom.create(function (ph) {
  ph.createPage(function (page) {
    page.open("http://github.com/", function (status) {
      console.log('Page Loaded');
      ph.exit();
    });
  });
});

请记住，为桥构建的脚本必须使用简单的PhantomJS脚本编写different。
