Error: Unable to find module 'opennebula' (Meteor.JS)

Question

我已经尝试过 meteorhacks:npm，但出现了同样的错误。

在 Meteor.JS 应用程序中，安装了 iron:router；我无法将 NPM 模块 "opennebula"（可从 https://github.com/OpenNebula/addon-nodejs 获得）加载到我的项目（在服务器端）；我收到如下堆栈跟踪：

I20150222-03:56:59.927(-5)? Exception while invoking method 'onLoad' Error: Cannot find module '/usr/local/lib/node_modules/opennebula'

指定的模块路径实际上包含从 NPM 安装的模块：

fox2 ~ # ls /usr/local/lib/node_modules/opennebula
./  ../  lib/  node_modules/  .npmignore  package.json  README.md  test/

因此，我的 server/__main__.js 文件包含以下代码：

if (Meteor.isServer){
  Meteor.methods({
    'onLoad': function(){
      var OpenNebula = Npm.require('/usr/local/lib/node_modules/opennebula'); // <== THIS LINE
      var one = new OpenNebula("user:pass", "http://127.0.0.1:2633/RPC2");

      one.version(function(err, data) {
        console.log(data);
      });

      return "Survey says...";
    }
  })
}

调用该函数的客户端代码如下：

if (Meteor.isClient) {
  callback = function(a){
    console.log('callback: ' + a);
  };
  Meteor.call('onLoad', callback);
}

流星应用程序包及版本如下：

fox2 app # meteor update
This project is already at Meteor 1.0.3.1, the latest release.
Your packages are at their latest compatible versions.

fox2 app # meteor list
autopublish      1.0.2  Publish the entire database to all clients
insecure         1.0.2  Allow all database writes by default
iron:router      1.0.7  Routing specifically designed for Meteor
jquery           1.11.3  Manipulate the DOM using CSS selectors
meteor-platform  1.2.1  Include a standard set of Meteor packages in your app

我做错了什么？

我发现这个模块在 Node.JS:

中甚至不起作用

fox2 Standalone # node -v 
v0.12.0

fox2 Standalone # node __main__.js
module.js:338
    throw err;
          ^

原来答案是：

OpenNebula 制作了一个糟糕的 NPM（节点包）。

我提交了一个拉取请求 (PR#3) 来解决这个问题。

Error: Unable to find module 'opennebula' (Meteor.JS)

javascript

node.js

meteor

npm

我已经尝试过 meteorhacks:npm，但出现了同样的错误。
