node.js - 如何使用 eleastic search 2.2.0 初始化 mongoosastic

Question

我在我的 Node.js 服务器中设置 mongoosastic 时遇到了麻烦。我按照视频讲座进行操作，但不起作用。

但是，有人说如果我降级elasticsearch版本就可以了。但我认为elasticsearch v2.2 也应该可以。

这是代码点亮。

var mongoose = require('mongoose');
var mongoosastic = require('mongoosastic');
var Schema = mongoose.Schema;

var ProductSchema = new Schema({
    category : {type : Schema.Types.ObjectId, ref : 'Category'}
    , name : String
    , price : Number
    , image : String
});

//Set Elastic Search
ProductSchema.plugin(mongoosastic, {
    hosts : [
        'localhost:9200'
    ]
});

module.exports = mongoose.model('Product', ProductSchema); 

这是错误。

从 Mongoosastic 的最新版本开始，它需要 Node.js 版本 >= 4.0

您可以在这里查看一些内容https://github.com/mongoosastic/mongoosastic/blob/master/CHANGELOG.md
