I am using node.js to run one app given by my professor on my chrome. Something wrong happen, but I don't know because I am a rookie. The structure is as follows:

/app
   /models
      answers.js
      questions.js
      sessions.js
      user.js
   passport.js
   qmanage.js
   routes.js
/config
   auth.js
   database.js
   mcd.js
package.json
/public
   some css png fonts jpg document
qloader.js
server.js
/views
   some ejs document

At first, it shows this problem:

module.js:457
    throw err;
    ^

Error: Cannot find module 'mongoose'
    at Function.Module._resolveFilename (module.js:455:15)
    at Function.Module._load (module.js:403:25)

    at Module.load (module.js:473:32)
    at tryModuleLoad (module.js:432:12)
    at Function.Module._load (module.js:424:3)

then, based on this help Node.js error Error: Cannot find module 'mongoose' I run npm install mongoose in my root path of project. Then I have those error below:

dyn143030:cse shen$ node server.js

I tried to find solution from this help Cannot find module '../build/Release/bson'] code: 'MODULE_NOT_FOUND' } js-bson: Failed to load c++ bson extension, using pure JS version but it seems not my case, because I am using OS X 10.11.3 

dyn143030:cse shen$ node -v
v6.5.0
dyn143030:cse shen$ npm -v
3.10.3

From my aspect, I think the system find bson someplace wrong, so how to modify it? Thanks! If any more information is need, please tell me.

I find in node_modules\bson\ext\index.js

and change path on 10th line

bson = require('../build/Release/bson'); to bson = require('bson');

You can try adding mongoose to the dependency list in the package.json file, or also doing >npm install mongoose in the project folder.
