如何使用 eleastic search 2.2.0 初始化 mongoosastic

Question

我在 node.js 服务器中设置 mongoosastic 时遇到了麻烦。跟着视频讲了，还是不行

但是人家说我降级elasticsearch版本就OK了。但我认为它也应该能够与 elasticsearch v2.2 一起使用。

这里是代码。

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。

由于 Mongoosastic 的最新版本需要 Node.js version >= 4.0
