操作系统：Mac OS X 环境：xcode command line tools、io.js 2.2.1、npm 2.11.0

app.js

var express = require('express'),
    cons = require('consolidate'),
    mongodb = require('mongodb');

package.json

{
  "name":"intro_npm",
  "version":"0.0.0",
  "description": "npm introduction",
  "main": "app.js",
  "dependencies": {
    "consolidate": "~0.9.1",
    "express": "~3.2.6",
    "mongodb": "~1.3.10"
  },
  "author": "Shaun Verch",
  "license": "BSD"
}

bash 执行npm install的结果

看起来安装应该没有问题但是执行$ iojs app.js的时候控制台输出：

Failed to load c++ bson extension, using pure JS version

为啥bson组建加载失败呢？install的时候也没有warning或者error。求指教

node_modules/mongodb/node_modules/mongodb-core/node_modules/bson/node_modules/bson-ext/ext/index.js 看下有惊喜。

引用 leapon这个和 io.js 没关系，在 nodejs 下也会出现。应该是你的build环境缺东西。 http://stackoverflow.com/questions/21656420/failed...

@leapon 也许吧，但总感觉那些WARN可能和io.js有关

找到原因了，是我的mongodb的版本老了把package.json里面的"mongodb": "~1.3.10"改成"mongodb": "^2.0.33" 然后执行 $ npm update 控制台输出

虽然看起来好多坑爹的警告，不过貌似不再会提示bson加载失败了。
