Ziel [Illuminate \ Verträge \ Routing \ ResponseFactory] nicht instantiable

Question

ich eine Antwort wie diese Rückkehr versuche:

return response()->json(['name' => 'Abigail', 'state' => 'CA']); 

jedoch habe ich Fehler:

Target [Illuminate\Contracts\Routing\ResponseFactory] is not instantiable. 

Jede Idee?

Hier ist meine composer.json:

{ 
    "name": "laravel/lumen", 
    "description": "The Laravel Lumen Framework.", 
    "keywords": [ 
    "framework", 
    "laravel",

Könnte spät sein, aber die Lösung gefunden.

In Bootstrap/app.php, Kommentar- der folgenden Zeile

$app->register(App\Providers\AppServiceProvider::class); 

dann in app \ Providers \ AppServiceProvider.php, Aktualisierungsregister Methode hinzufügen:

public function register() 
{ 
    $this->app->singleton('Illuminate\Contracts\Routing\ResponseFactory', function ($app) { 
     return new \Illuminate\Routing\ResponseFactory(
      $app['Illuminate\Contracts\View\Factory'], 
      $app['Illuminate\Routing\Redirector'] 
     ); 
    }); 
}
