Couchbase上的N1QL和節點

Question

我想用Node.js SDK中的Couchbase來使用N1QL。這裏是我的代碼：

var config = require('../../config/init'); 
     var N1qlQuery = require('couchbase').N1qlQuery; 
     var query = N1qlQuery.fromString("SELECT * FROM users"); 
     var db = couchbaseService(); 
     console.log('start'); 
     db.query(query, function(err, result) { 
      if (err) { 
       console.log('inside err'); 
       console.log(err); 
       return; 
      } 
      console.log('No error in NIQL'); 
      console.log(result.object); 
     }); 

以下是錯誤：

TypeError: Cannot read property 'length' of undefined 
    at Bucket._query (/vagrant_data/xxxxx/node_modules/couchbase/lib/bucket.js:331:52) 
    at Bucket.query (/vagrant_data/xxxxx/node_modules/couchbase/lib/bucket.js:607:17)

    at callbacks (/vagrant_data/xxxxx/node_modules/sails/node_modules/express/lib/router/index.js:167:11) [TypeError: Cannot read property 'length' of undefined] 

請注意，問題是不是連接到木桶或服務器。我使用.get（）和.insert（），他們正在努力fine.some缺少在N1QL庫。任何人都可以幫忙？

您必須啓用在給定桶n1ql：

bucket.enableN1ql(serverUrl+":8093") 

更可以在這裏找到： http://docs.couchbase.com/sdk-api/couchbase-node-client-2.0.0/Bucket.html#enableN1ql
