Klasse 'Benutzer' nicht gefunden Laravel 5.2 direkt nach der Neuinstallation

Question

Ich habe gerade Laravel 5.2 Anwendung neu installiert, indem ich die Anleitung in der Dokumentation - https://laravel.com/docs/5.2#installing-laravel.

Es ist nicht das erste Mal, dass ich das gemacht habe, aber ich hatte vorher kein Problem. Ich erhalte diese Fehlermeldung:

FatalThrowableError in routes.php Linie 15: Fatal error: Class 'User' nicht

gefunden

ich meine routes.php Ich habe nur:

Route::get('/', function() { 
return view('welcome'); }); 

I kann nicht verstehen, wo das Problem sein kann. Ich habe diesen Fehler bei Neuinstallation, noch nie zuvor mit einem solchen Problem konfrontiert. Jede Hilfe wäre willkommen.

Hier ist ein Full-Screenshot mit Fehler: Screenshot with error

Voll routes.php Datei:

<?php 

/* 
|-------------------------------------------------------------------------- 
| Application Routes 
|-------------------------------------------------------------------------- 
| 
| Here is where you can register all of the routes for an application. 
| It's a breeze. Simply tell Laravel the URIs it should respond to 
| and give it the controller to call when that URI is requested. 
| 
*/ 

Route::get('/', function() { 
    return view('welcome'); 
});
