Fatal Error when Running SLIM

When attempting the task of running Slim (2:30 mark), after I refresh my local host I do not receive the '404 error' that instructor Hampton does. Instead, I receive a 'Fatar error: Class 'Slim\Slim' not found in C:\xampp\htdocs\building_website_w_PHP\index.php on Line 9.

I believe it is an issue with my file management; wondering if anyone knows why I would receive such an error??

Thank you~

I am getting that same thing. I now have another error, but I was able to resolve the Slim auto loading error by backing out to directory and reentering composer require slim/slim:~2.0.

Are your composer, composer.json, composer.lock, and vendor folder in the folder where your project lives? That was my problem when I got that error.
