package中添加依赖包（monodb）以后无法正常安装

求教为什么在package中加入新的依赖包以后执行install失败？？代买如下

"dependencies": {
    "body-parser": "~1.13.2",
    "cookie-parser": "~1.3.5",
    "debug": "~2.2.0",
    "ejs": "~2.3.3",
    "express": "~4.13.1",
    "morgan": "~1.6.1",
    "serve-favicon": "~2.3.0"
    "mongodb": "*"
  }
  

加入mongodb以后再当前目录执行npm install，显示如下错误

D:\microblog\microblog>npm install
npm ERR! install Couldn't read dependencies

请问出现这个的原因啊？很神奇啊为什么会提示出现'm'有问题啊？只有mongodb无法正常安装啊
