Problem with routes in laravel 4

I am new to laravel and am learning it now. I give the following route in a fileroutes.php

Route::resource('contacts', 'ContactsController');

      

        
        
        
      

    

But when I load my page in the browser it gives me the following error

Unhandled Exception

Message:

Call to undefined method Laravel\Routing\Route::resource()
Location:

/Users/zafarsaleem/Sites/learning-laravel/application/routes.php on line 35

      

        
        
        
      

    

My complete route.php file is below

Route::resource('contacts', 'ContactsController');

Route::get('/', function()   //<------- This is line 35
{
    return View::make('home.index');
});

      

        
        
        
      

    

How do I remove this error?

Edit

ContactsController code is below and I want to use index () function

class ContactsController extends BaseController {

/**
 * Display a listing of the resource.
 *
 * @return Response
 */
public function index()
{
    Contact::all();
}

/**
 * Show the form for creating a new resource.
 *
 * @return Response
 */
public function create()
{
    //
}

/**
 * Store a newly created resource in storage.
 *
 * @return Response
 */
public function store()
{
    $input = Input::json();

    Contact::create(array(
        'first_name' => $input->first_name
        'last_name' => $input->last_name
        'email_address' => $input->email_address
        'description' => $input->description
    ));
}

/**
 * Display the specified resource.
 *
 * @return Response
 */
public function show($id)
{
    return Contact::find($id);
}

/**
 * Show the form for editing the specified resource.
 *
 * @return Response
 */
public function edit($id)
{
    //
}

/**
 * Update the specified resource in storage.
 *
 * @return Response
 */
public function update($id)
{
    $contact = Contact::find($id);
    $input = Input::json();

    $contact->first_name = $input->first_name;
    $contact->last_name = $input->last_name;
    $contact->email_address = $input->email_ddress;
    $contact->description = $input->description;

    $contact->save();
}

/**
 * Remove the specified resource from storage.
 *
 * @return Response
 */
public function destroy($id)
{
    return Contact::find($id)->delete();
}

}

      

        
        
        
      

    

Edit 2

I tried both of the following routes but ended up below error

Route::resource('contacts', 'ContactsController', ['only', => ['index']]);
Route::get('contacts','ContactsController@index');

      

        
        
        
      

    

After reinstalling laravel 4, now I am getting the following error

404 Not Found

The requested URL /contacts was not found on this server.

Edit 3

Here is what I now edited "/private/etc/apache2/users/.conf" and changed from "AllowOverride None" to "AllowOverride All" and then restarted my Apache server. Now I am getting the following error

403 Forbidden

You don't have permission to access /contacts on this server.

Why don't I have permission for this contact controller? Now it makes me crazy.

Here is my .htaccess file

<IfModule mod_rewrite.c>
Options -MultiViews
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ index.php [L]
</IfModule>
