Strange Node.js behavior - won't render a web page

I am running the latest Node.js version (0.8.14 as of this writing) on OS X Mountain Lion (10.8.2). I am writing a simple chat application, and I have one server.js file, one index.html file and one style.css file.

The contents of the server.js file are the following:

var http = require('http')
, fs = require('fs')
, path = require('path')
, mime = require('mime')
, cache = {};

function send404(response) {
response.writeHead(404, {'Content-Type': 'text/plain'});
response.write('Error 404: resource not found.');
response.end();
}

function sendFile(response, filePath, fileContents) {
response.writeHead(
    'content-type',
    mime.lookup(path.basename(filePath))
);
response.end(fileContents);
}

function serveStatic(response, cache, absPath) {
if (cache[absPath]) {
    sendFile(response, absPath, cache[absPath]);
} else {
    path.exists(absPath, function(exists) {
        if (exists) {
            fs.readFile(absPath, function(err, data) {
                cache[absPath] = data;
                sendFile(response, absPath, data);
            });
        } else {
            send404(response);
        }
    });
}
}

var server = http.createServer(function(request, response) {
var filePath = false;

if (request.url == '/') {
    filePath = 'public/index.html';
} else {
    filePath = 'public' + request.url;
}

if (!filePath) {
    send404(response);
} else {
    var absPath = './' + filePath;
    serveStatic(response, cache, absPath);
}
});

server.listen(3000, function() {
console.log("Server listening on port 3000.");
});

I think it's no use to post the content of index.html and style.css page because they consist of standard HTML and CSS stuff. When I run the app with

node server.js

and visit the app at

localhost:3000

I get the following response in the browser (also, it takes about 2 - 3 minutes to actually load the page):

HTTP/1.1 content-type text/html
Date: Thu, 15 Nov 2012 20:08:16 GMT
Connection: keep-alive
Transfer-Encoding: chunked

0

instead of rendering an index.html web page. Where am I going wrong?

Update: I've restarted Aptana Studio, and now when I run

node server.js

I get the following output:

throw err;
      ^
Error: Cannot find module '/Users/petarpetrovic/Documents/Aptana Studio 3 Worksp
ace/chatroom/sever.js'

at Module.runMain (module.js:492:10)
at process.startup.processNextTick.process._tickCallback (node.js:244:9)

Update 2: When I run

npm install

And then run server.js file, I get the following output:

HTTP/1.1 content-type text/html
