我正在尝试将 N1QL 与 Couchbase 的 Node.js SDK 一起使用。这是我的代码：

 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);
        });

这是错误：

 TypeError: Cannot read property 'length' of undefined

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

请注意，问题不在于连接到 bucker 或服务器。我使用了 .get() 和 .insert() 并且它们工作正常。N1QL 库中缺少一些东西。有人可以帮忙吗？

您必须在给定存储桶上启用 n1ql：

bucket.enableN1ql(serverUrl+":8093")

更多可以在这里找到：http: //docs.couchbase.com/sdk-api/couchbase-node-client-2.0.0/Bucket.html#enableN1ql
