未捕获的PHP异常Symfony \ Component \ HttpKernel \ Exception \ NotFoundHttpException：“找不到”GET /“的路由

I just started following a symfony 4 tutorial I set up the whole project with composer and got the index file showing up in browser http://127.0.0.1:8000/

I'm stuck on the very first Router/Controller/View example The route is not working properly or at all. I always get a 404 error.

<?php


namespace App\Controller;

use Symfony\Component\HttpFoundation\Response;

class LuckyController
{
    public function number()
    {
        $number = random_int(0, 100);

        return new Response(
            '<html><body>Lucky number: '.$number.'</body></html>'
        );
    }
}


# the "app_lucky_number" route name is not important yet
app_lucky_number:
  path: /lucky/number
  controller: App\Controller\LuckyController::number

I'm out of ideas, I've looked everywhere on google and did not found a solution.

    Make sure your contorller is on the right path src/Controller/

    Example 

    namespace App\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\Routing\Annotation\Route;

class LuckyController extends AbstractController
{

  public function number()
  {
    echo __LINE__;die();
  }
}

    Check the config/routes.php files have the correct routes

    namespace Symfony\Component\Routing\Loader\Configurator;

use App\Controller\LuckyController;

return function (RoutingConfigurator $routes) {
   // Matches /lucky exactly
   $routes->add('lucky_number', '/lucky')
      ->controller([LuckyController::class, 'number'])
   ;

};

    OR

    Change your YAML to

    # the "app_lucky_number" route name is not important yet
app_lucky_number:
path: /lucky
controller: App\Controller\LuckyController::number

    After doing this access this URL http://127.0.0.1:8000/lucky
