貓鼬有沒有方法`連接`

Question

我使用npm在node.js上安裝了貓鼬。當我嘗試使用此代碼連接：

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

我得到這個錯誤：

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 Array.0 (module.js:479:10) 
    at EventEmitter._tickCallback (node.js:192:40) 

當做終端mongo，我得到：

MongoDB shell version: 2.0.2 
connecting to: test 

任何人都知道爲什麼沒有connect()方法在貓鼬對象？

而不是

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

使用

mongoose = require('mongoose/');
