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 npm ERR! Windows_NT 6.1.7601 npm ERR! argv "D:\\node\\node.exe" "D:\\node\\node_modules\\npm\\bin\ " "install" npm ERR! node v4.4.1 npm ERR! npm v2.14.20 npm ERR! file D:\microblog\microblog\package.json npm ERR! code EJSONPARSE npm ERR!

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
