Openshift無法加載C++ bson擴展/無法找到模塊（'swig'）

Question

我想讓我的節點/ mongo/express應用程序在Openshift上工作。它在本地工作，但在Openshift上，我得到一個錯誤：無法找到模塊（'swig'）我已經將它添加到package.json中的依賴項中，如下所示。

而且我需要在我的server.js像這樣：

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

完整的錯誤讀取：

這是與未加載C++ BSON擴展問題，這是造成這些其他錯誤？有沒有解決這個問題的方法？它在本地工作正常，只是不在openshift。 在此先感謝您的幫助！

我刪除它和故宮運行安裝重新安裝在我的節點模塊文件夾和固定找不到模塊（「痛飲」）錯誤，但是，現在我得到一個錯誤，它無法找到模塊'../helpers'，這似乎是一個文件夾，應該存在於node-modules文件夾中的swig內部。我跑了搜索，其中被列入它，這就是我的了：

Searching 744 files for "../helpers" 

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

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'); 
    3

    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'); 

難道這是因爲我使用痛飲的版本不正確？

好的，通過確保它們通過git添加到openshift來修復該錯誤。現在，我得到這個，我不知道它是什麼尋找：

Answer 1

我認爲你的問題的第一部分是某種損壞的模塊 - 或許是由於gcc的未安裝，但也許不是。

我的建議是你擦去節點模塊，並使用NPM緩存和重新獲取模塊：

rm -rf node_modules 
npm cache clean 
npm install 

一旦你這樣做，你經歷了打開文件「//layout.html」

問題

這似乎是一個已知問題，由initializing swig and to tell it where to find the template解決。
