当我尝试在Couchbase Node.js服务器上运行简单测试时，出现“参数错误”错误

Question

var couchbase = require("couchbase");



var cluster = new couchbase.Cluster('127.0.0.1:8091');
var bucket = cluster.openBucket('beer-sample', function(err) {
    if (err) {

        throw err;
    }



    bucket.get('aass_brewery-juleol', function(err, result) {
        if (err) {

            throw err;
        }

        var doc = result.value;

        console.log(doc.name + ', ABV: ' + doc.abv);

        doc.comment = "Random beer from Norway";

        bucket.replace('aass_brewery-juleol', doc, function(err, result) {
            if (err) {

                throw err;
            }

            console.log(result);


            process.exit(0);
        });
    });
});

Here is my file. It's the example from here : http://docs.couchbase.com/developer/node-2.0/hello-couchbase.html

So when i try to run the server with "nodejs test1.js" i get "Incorrect argument" error.

At bucket.js, module.js and in cluster.js into node_modules/couchbase/lib/

I have installed couchbase and i have full nodejs installed. I'm new in this and i cant understand where is my mistake. Maybe something with the versions of the couchbase or the node version i dunno.

Here is my full error which i get into the terminal:

Error: Incorrect argument

The "Canonical" format for connecting to a cluster is couchbase://host where host in your case is localhost .

Depending on the version you're using, newer enhancements may have been added to allow for the common host:8091 antipattern, but would still be incorrect.

Chances are your code can still work if you upgrade to a newer version - but you should still use the couchbase:// variant (without the port).
