1.我出现的错误指令:

E:\Front\nodjsjs\node_modules\mongoose\lib\index.js:330
      throw new mongoose.Error.MissingSchemaError(name);
            ^
MissingSchemaError: Schema hasn't been registered for model "Movie".
Use mongoose.model(name, schema)
    at Mongoose.model (E:\Front\nodjsjs\node_modules\mongoose\lib\index.js:330:1

2.我的npm list，关于mongo的部分。我只是npm和bower安装了东西，不知道mongodb要不要另外安装。

│   └─┬ acorn-globals@1.0.5
│     └── acorn@2.2.0
├─┬ mongodb@2.0.40

3.另外，我在命令行中输入mongo，不能进入mongo的命令行

$ mongo
sh.exe": mongo: command not found

如何开服务啊

mongodb 要把服务开着，必须要http://localhost:27017/能访问，OK
