Openshift无法加载c ++ bson扩展/无法find模块（'swig'）
我试图让我的节点/ 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find模块（'sw'）我已经将它添加到我的依赖在package.json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中像这样：
var swig = require('swig'); var cons = require('consolidate'); //later app.engine('html', cons.swig);
完整的错误读取：

这是未能加载c ++ bson扩展，这是导致这些其他错误的问题？ 有没有办法解决这个问题？ 它在当地正常工作，只是没有openshift。 在此先感谢您的帮助！
我重新安装我的node-modules文件夹删除它，并运行npm安装，并修复了无法find模块（'swig'）错误，但是，现在我得到一个错误，它无法find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中。 我search了它被包含在哪里，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 C:\Repositories\meanapps\node_modules\swig\lib\tags\for.js: 1: var helpers = require('../helpers'), 2 _ = require('underscore'); 3 C:\Repositories\meanapps\node_modules\swig\lib\tags\if.js: 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了一个不正确的swig版本吗？
好的，通过确保它们通过git添加到openshift来修复这个错误。 现在，我得到这个，我不知道它在找什么：

我认为你的问题的第一部分是某种损坏的模块 – 可能是由于没有安装gcc，但可能不是。
我的build议是擦拭你的节点模块，npmcaching并重新获取模块使用：
rm -rf node_modules npm cache clean npm install
一旦你这样做，你遇到了问题打开一个文件“//layout.html”
这似乎是一个已知的问题，通过初始化swig解决， 并告诉它在哪里可以find模板 。
