PHP Slim composer - Not Found

Hello, Am just in the middle of Build A Basic PHP Website and Hempton was using Slim Framework, everything is going fine until i get to installing Slim. Hempton used v2 in the tutorial and have manage to include the "^3.0" in my composer.json file.


    "name": "root/workspace",
    "require": {
        "slim/slim": "^3.3"
    "authors": [
            "name": "Olamilekan Oshodi",
            "email": "*****ter@gmail.com"

Here is the my index file code.


require 'vendor/autoload.php';

//$log = new Monolog\Logger('name');
//$log->pushHandler(new Monolog\Handler\StreamHandler('app.txt', Monolog\Logger::WARNING));

// installing Slim Framework
$app = new Slim\App();

// Slim Framework routing
$app->get('/hello/{name}', function ($name) {
    echo "Hello, $name";


//here is the error am getting.
Fatal error: Uncaught Error: Class 'Slim\App' not found in /home/treehouse/workspace/index.php:11 Stack trace: #0 {main} thrown in /home/treehouse/workspace/index.php on line 11

Is there some thing am not adding to it, or missing? please help.
