Node JS Binding error when trying to use IBM_DB - node.js

I am getting the below error when trying to use IBM_DB for db2 access.
$ node nodetest.js

Error: Module version mismatch. Expected 47, got 46.

Here is the code I'm using:
var http = require("http");
var ibmdb = require("ibm_db");
console.log("Test program to access DB2 sample database");
http.createServer(function (request, response) {
response.writeHead(200, {'Content-Type': 'text/plain'});
response.end('Hello World\n');
}).listen(8081);
console.log('Server running at 127.0.0.1:8081/');
Can someone please help me on this ?

I know this is a 1 year old question but I think it requires at least one correct explanation/answer for that question here, so that future readers might not get confused.
Error: Module version mismatch. Expected 47, got 46.
You will encounter with this error mostly on Windows platform, and this is actually not a bug or defect, this is simply because node-ibm_db does not support particular node version (which you are using for installing node-ibm_db on windows platform).
Reason: node-ibm_db provides pre-compiled node binaries within the module for particular main node-versions (like 4.x, 6.x etc),module do not compile at installing time (on windows only), it uses the pre-compiled binaries to installation and setup.
Hence if you use a latest major version of nodejs and specifically that,- which node-ibm_db is not supporting yet (or simply pre-compiled binaries are not available), you will get this error.
