我有一些 node.js 代码正在使用jsdom,我需要jquery.min.js后端 css 选择器的文件。事情在本地运行良好,但如果我使用vmc pushon部署api.cloudfoundry.com,它给了我502 Bad Gateway nginx

我假设我必须在 package.json 中声明所有依赖项,就像这里http://blog.nodejitsu.com/package-dependencies-done-right

但是,我不知道如何包含jquery.min.js. 现在它在/lib文件夹而不是/node_modules文件夹中(因为它不是节点模块)。

有人可以帮助我了解如何为 Cloud Foundry 包含正确的依赖项和其他额外的 .js 文件吗?

更新 1:

这是我删除一堆东西后的代码。如果我注释掉jsdom.env,则没有错误。

var port = (process.env.VMC_APP_PORT || 3000);
var host = (process.env.VCAP_APP_HOST || 'localhost');
var http = require('http');

var request = require('request'),
    jsdom = require('jsdom');

http.createServer(function (req, res) {
  request({ uri:'http://www.google.com' }, function (error, response, body) {
    if (error && response.statusCode !== 200) {
      console.log('Error when contacting the url')
    }

    jsdom.env({
      html: body,
      scripts: [
        'lib/jquery.min.js'
      ]
    }, function (err, window) {
    });

    res.writeHead(200, {'Content-Type': 'text/plain'});
    res.write(body);
    res.end('\n');

  });

}).listen(port, host);

这是我在使用时看到的vmc logs hp-myapp

Using manifest file manifest.yml

它不能被上下文化,因为我localhost:3000跑得很好https://github.com/tmpvar/jsdom/issues/436

window.document 将在 Cloud Foundry 中返回 null,因为它依赖于服务器上存在的实际浏览器 dom。
