'Uncaught Error: Class 'Illuminate\Foundation\Application' not found

Could someone tell me what exactly this error is? searched everywhere and I could find some solutions like composer install, composer update,composer update --no-scripts.

I removed the

require __DIR__.'/../vendor/autoload.php';
and replaced it with the

$compiledPath = __DIR__.'/../vendor/compiled.php';

And now I have reached a point where I cant find a better solution, any help would be appreciated.

ttt-desktop:/var/www/html/equity3$ php artisan
    PHP Fatal error:  Uncaught Error: Class 'Illuminate\Foundation\Application' not found in /var/www/html/equity3/bootstrap/app.php:14
    Stack trace:
    #0 /var/www/html/equity3/artisan(24): require_once()
    #1 {main}
      thrown in /var/www/html/equity3/bootstrap/app.php on line 14
    ttt-desktop:/var/www/html/equity3$ 

I have my project in /var/www/HTML/equity3 and I am unable to run Php artisan serve.

My autoload.php looks like this

// autoload.php @generated by Composer
require_once __DIR__ . '/composer/autoload_real.php';

return ComposerAutoloaderInit9015d85c021292bc41e4d5a5d1794f3f::getLoader();

Maybe you did forget to do a composer install . :)
Or maybe something is missing in your composer.json.
