Openshift无法加载C++ bson扩展/无法找到模块（'swig'）

Question

我想让我的节点/ mongo/express应用程序在Openshift上工作。它在本地工作，但在Openshift上，我得到一个错误：无法找到模块（'swig'）我已经将它添加到package.json中的依赖项中，如下所示。

而且我需要在我的server.js像这样：

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

这是与未加载C++ BSON扩展问题，这是造成这些其他错误？有没有解决这个问题的方法？它在本地工作正常，只是不在openshift。 在此先感谢您的帮助！

我删除它和故宫运行安装重新安装在我的节点模块文件夹和固定找不到模块（“痛饮”）错误，但是，现在我得到一个错误，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。我跑了搜索，其中被列入它，这就是我的了：

Searching 744 files for "../helpers" 

C:\Repositories\meanapps\node_modules\swig\lib\tags\else.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

    1: var helpers = require('../helpers'),

    3 

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

难道这是因为我使用痛饮的版本不正确？

好的，通过确保它们通过git添加到openshift来修复该错误。现在，我得到这个，我不知道它是什么寻找：

Answer 1

我认为你的问题的第一部分是某种损坏的模块 - 或许是由于gcc的未安装，但也许不是。

我的建议是你擦去节点模块，并使用NPM缓存和重新获取模块：

rm -rf node_modules 
npm cache clean 
npm install 

一旦你这样做，你经历了打开文件“//layout.html”

问题

这似乎是一个已知问题，由initializing swig and to tell it where to find the template解决。
