Question

我在node.js服务器中设置mongoosastic时遇到了麻烦。我跟着视频讲座，但它不起作用。

然而，人们说如果我降级弹性搜索版本，那就没关系了。但我认为它应该能够与elasticsearch v2.2一起使用。

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。

自 Mongoosastic 的最新版本以来，它需要Node.js version >= 4.0
