Openshift无法加载c bson扩展/无法找到模块（'swig'）

我想让我的node / mongo / express应用程序在Openshift上运行 . 它在本地工作，但在Openshift上我得到一个错误：找不到模块（'swig'）我已将它添加到package.json中的依赖项中，如下所示 .

"dependencies": {
"bcrypt-nodejs": "~0.0.3",
"consolidate": "~0.9.1",
"express": ">=3.x",
"mongodb": "~1.3.9",
"swig": "~0.14.0",
"validator": "~1.1.3"
},
"devDependencies": {},
"bundleDependencies": [],

我需要在我的server.js中这样：

var swig = require('swig'); var cons = require('consolidate'); 
//later app.engine('html', cons.swig);

这是无法加载c bson扩展的问题，这是导致这些其他错误吗？有没有解决这个问题的方法？它在本地工作正常，而不是在openshift . 在此先感谢您的帮助！

我重新安装了我的node-modules文件夹，删除它并运行npm install并修复了无法找到模块（'swig'）错误，但是，现在我收到一个错误，它无法找到模块'../helpers' ，这似乎是一个文件夹，应该存在于node-modules文件夹中的swig内部 . 我搜索了它被包含的位置，这就是我得到的：

Searching 744 files for "../helpers"

C:\Repositories\meanapps\node_modules\swig\lib\tags\else.js:
    1: var helpers = require('../helpers'),
    2    _ = require('underscore');
    3  

C:\Repositories\meanapps\node_modules\swig\lib\tags\filter.js:
    1: var helpers = require('../helpers'),
    2    _ = require('underscore');
    3

    1: var helpers = require('../helpers'),
    2    _ = require('underscore');

    1: var helpers = require('../helpers'),
    2    _ = require('underscore');
    3  

C:\Repositories\meanapps\node_modules\swig\lib\tags\import.js:
    1: var helpers = require('../helpers'),
    2    _ = require('underscore');
    3  

C:\Repositories\meanapps\node_modules\swig\lib\tags\include.js:
    1: var helpers = require('../helpers'),
    2    _ = require('underscore');
    3  

C:\Repositories\meanapps\node_modules\swig\lib\tags\set.js:
    1: var helpers = require('../helpers'),
    2    _ = require('underscore');

这可能是因为我使用的是不正确的swig版本吗？

好的，通过确保它们通过git添加到openshift来修复该错误 . 现在，我得到了这个，我不知道它在寻找什么：
