"Cannot GET /" with Connect on Node.js

I'm trying to start serving some static web pages using connect like this:

var connect = require("connect");
var nowjs = require("now");
var io = require("socket.io");


var app = connect.createServer(
  connect.static(__dirname + '/public')
);

app.listen(8180);

So I added a simple index.html at the /public directory on the same directory as the app.js file is, but when I try to view the page on my browser I get this response from node:

Cannot GET /

What I'm doing wrong and how I can correct it?

You'll see the message Cannot GET / if you don't specify which page it is that you're trying to get, in other words if your URL is something like http://localhost:8180. Make sure you enter a page name, e.g. http://localhost:8180/index.html.

You may be here because you're reading the Apress PRO AngularJS book...

As is described in a comment to this question by KnarfaLingus:

[START QUOTE]

The connect module has been reorganized. do:

npm install connect 

and also

npm install serve-static

Afterward your server.js can be written as:

var connect = require('connect');
var serveStatic = require('serve-static'); 
var app = connect(); 

app.use(serveStatic('../angularjs')); 

app.listen(5000);

[END QUOTE]

Although I do it, as the book suggests, in a more concise way like this:

var connect = require('connect');
var serveStatic = require('serve-static');

connect().use(
    serveStatic("../angularjs")
).listen(5000);

This code should work:

var connect = require("connect");

var app = connect.createServer().use(connect.static(__dirname + '/public'));

app.listen(8180);

Also in connect 2.0 .createServer() method deprecated. Use connect() instead.

var connect = require("connect");

var app = connect().use(connect.static(__dirname + '/public'));

app.listen(8180);

You might be needed to restart the process if app.get not working. Press ctl+c and then restart node app.
