node.js file name is reserved in NodeJS. I too got the same error. I renamed my file to "test.js" and it worked...

var http = require("http");
http.createServer(function(request, response) {
response.writeHead(200, {"Content-Type": "text/plain"});
response.write("Hello World OKKK");
response.end();
}).listen(8888);

command prompt> node test.js
URL => http://localhost:8888 and it prints "Hello World OKKKK" on the browser.
