Node.js 响应节点处的请求错误\u modules/elasticsearch/src/lib/transport.js:264:15

我对ElasticSearch非常无知，对NodeJs几乎没有经验。我使用NodeJs+MongoDb创建了一些积垢。我必须从MongoDb改为ElasticSearch（这是强制性的）。拜托，我不想将MOngoDb与ElasticSearch进行比较，所以不要尝试

我遵循这里的例子

https://blog.raananweber.com/2015/11/24/simple-autocomplete-with-elasticsearch-and-node-js/

我已经成功地开始了弹性搜索。我可以看到：

nodejs express.js-elasticsearch-autocomplete-demo-master # curl --noproxy -XGET 'http://127.0.0.1:9200/?pretty'
{
  "name" : "-em7X-s",
  "cluster_name" : "elasticsearch",
  "cluster_uuid" : "cqJUaPcFREe4wX_YyYWoFg",
  "version" : {
    "number" : "5.2.1",
    "build_hash" : "db0d481",
    "build_date" : "2017-02-09T22:05:32.386Z",
    "build_snapshot" : false,
    "lucene_version" : "6.4.1"
  },
  "tagline" : "You Know, for Search"
}

但是，当我尝试启动上面的示例或访问时，我分别得到以下错误：

/dev/samples/express.js-elasticsearch-autocomplete-demo-master $ npm start

我很困惑该检查什么。如有任何建议，将不胜感激。我的最终目标是了解如何从NodeJs应用程序连接到ElasticSearch

DemeCarvO你知道问题出在哪里吗？好吧，没关系，elastic 5.2对我来说也有一些突破性的变化。请让我知道如果你发现了问题，你知道问题是什么吗？好吧，没关系，弹性5.2对我来说有一些突破性的变化。如果你发现了问题，请告诉我
