错误:在Mac上找不到模块'../build/Release/bson'

Question

我正在使用node.js运行我的教授在我的chrome上给出的一个应用程序.发生了一些错事,但我不知道,因为我是一名新秀.结构如下:

/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

首先,它显示了这个问题:

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.require (module.js:483:17)

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

然后,基于此帮助Node.js错误错误:找不到模块'mongoose'我npm install mongoose在项目的根路径中运行.然后我有以下错误:

dyn143030:cse shen$ node server.js 
{ Error: Cannot find module '../build/Release/bson'

我试图从这个帮助找到解决 找不到模块"../build/Release/bson"]代码:'MODULE_NOT_FOUND’} JS-BSON:无法加载C++ BSON扩展,使用纯JS版本 ,但它似乎没有我的情况下,因为我使用的是OS X 10.11.3

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

从我的角度来看,我认为系统发现某个地方错了,所以如何修改呢？谢谢!如果需要更多信息,请告诉我.

Answer 1

我在node_modules\bson\ext\index.js中找到

并在第10行更改路径

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