通过猫鼬连接到数据库时出现问题.
 当我使用这段代码

var mongoose = require('mongoose').Mongoose;
var db = mongoose.connect('mongodb://localhost/goaljuice');

然后我有问题.
 这是我的问题

TypeError: Object function Mongoose() {
  this.connections = [];
  this.plugins = [];
  this.models = {};
  this.modelSchemas = {};
  this.options = {};
  this.createConnection(); // default connection
} has no method 'connect'
==================================

这是我的结构文件夹：

-express_example
--app.js
--node_modules
------express, jade, mongodb, mongooses, stylus
--public
--router
--views

解决方法:

代替

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

尝试

var mongoose = require('mongoose');
