node.js - Mongoose 没有方法 `connect`

Question

我使用 npm 在 node.js 上安装了 mongoose。当我尝试连接此代码时:

mongoose = require('mongoose/').Mongoose
@db = mongoose.connect("mongodb://localhost/test")

我收到这个错误:

node.js:201
        throw e; // process.nextTick error, or 'error' event on first tick
              ^
TypeError: Object function Mongoose() {
  this.connections = [];
  this.plugins = [];
  this.models = {};
  this.modelSchemas = {};
  this.options = {};
  this.createConnection(); // default connection
} has no method 'connect'

    at EventEmitter._tickCallback (node.js:192:40)

当在终端中执行 mongo 时，我得到:

MongoDB shell version: 2.0.2
connecting to: test

谁知道为什么mongoose对象中没有connect()方法？

代替

mongoose = require('mongoose/').Mongoose;

使用

mongoose = require('mongoose/');
