Question

I got this "stacktrace" when trying to display my website. I am new to this, but the error looks to be to something regarding the laravel's system-files?

This is my route.php file.
//(php open tag) Route::get('/', 'HomeController#index');
and my HomeController.php
<?php namespace App\Http\Controllers;
use Illuminate\Routing\Controller;
class HomeController extends Controller {
public function index()
{
return view ('hello');
}
}
And this is my view file hello.php
<doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Laravel 5</title>
</head>
<body>
Welcome to Laravel 5
</body>
</html>

Answer 1

I was getting the same issue for some authentication matter. I get solution by following the 2 steps below:
1. Put "league/oauth2-server": "4.1.*" on the require section of your composer.json file.
2. run 'composer update' command on terminal.
I hope it will help you.

Answer 2

Replace use Illuminate\Routing\Controller; with use App\Http\Controllers\Controller; and also do
composer dump-autoload
