Creating temporary view in couchdb using node-couchdb-api

I am trying to connect couchdb using node-couchdb-api at nodejs level as mentioned in the following link http://dominicbarnes.us/node-couchdb-api/.My couchdb version is 1.1.1 and nodejs version is 0.6.10.

For creating temporary view as mentioned in api http://dominicbarnes.us/node-couchdb-api/api/database/tempView.html I have written the following code.

var couchdb = require("couchdb-api");
var server = couchdb.srv(localhost, 5984, false, false);
var db = server.db("test");
var map = function (doc) {
emit(null, 1);
};
var reduce = "_sum";
var query = { include_docs: true };
db.tempView(map, reduce, query, function (err, response) {
console.log(response);
});

But i am facing the following problem.

C:\Program Files\nodejs\node_modules\couchdb-api>node server.js
node.js:201
throw e; // process.nextTick error, or 'error' event on first tick
          ^
