javascript node.js couchbase nosql

Javascript 使用node.js启用Couchbase N1QL引擎,javascript,node.js,couchbase,n1ql,nosql,Javascript,Node.js,Couchbase,N1ql,Nosql,我正在尝试使用couchbasenpm包运行一些N1QL查询。以下是我在运行代码之前采取的步骤：在OSX上安装并执行Couchbase 导航到：8091并设置将凭证以及啤酒样品桶已将N1QL DP4下载到文件夹中已启用cbq引擎如下： /cbq引擎-数据存储=http://localhost:8091 创建一个此时，我的localhost:8091（主Couchbase集群）和localhost:8093（DP4引擎）都处于活动状态下面是我在node.js客户端尝试运行简单N1QL查

我正在尝试使用

couchbase

npm包运行一些N1QL查询。以下是我在运行代码之前采取的步骤：

在OSX上安装并执行Couchbase

导航到：8091并设置将凭证以及

啤酒样品桶


已将N1QL DP4下载到文件夹中
已启用cbq引擎如下：
/cbq引擎-数据存储=http://localhost:8091
创建一个
此时，我的localhost:8091
（主Couchbase集群）和localhost:8093
（DP4引擎）都处于活动状态
下面是我在node.js客户端尝试运行简单N1QL查询时使用的代码：
var colors = require('colors'); // for console.log
var couchbase = require('couchbase');
var N1qlQuery = require('couchbase').N1qlQuery; // get query object
var myCluster = new couchbase.Cluster('couchbase://localhost:8091'); // connect to live local cluster
var myBucket = myCluster.openBucket(); // open bucket
myBucket.enableN1ql(['http://localhost:8093/']); // enable n1ql as per documentation (http://docs.couchbase.com/developer/node-2.0/n1ql-queries.html) - I also tried :8091, same result
var query = N1qlQuery.fromString('SELECT * FROM `beer-sample` LIMIT 10');

setTimeout(function() {
  myBucket.query(query, function(err, res) {
    if (err) {
      console.log('query failed'.red, err);
      return;
    }
    console.log('success!', res);
  });
}, 2000); // just in case connecting takes a second or something?

结果如下：
查询失败{[错误：无法连接到存储桶]代码：24}
我尝试了所有方法，但找不到任何文档来解决这个问题。发生什么事了
