Исключение при использовании промежуточного ПО Entrust в Laravel 5.1

Я установил вверять пакет в моем приложении Laravel 5.1, добавив его в мой файл composer.json и запустив обновление композитора и следуя всем инструкциям к письму. Я пытаюсь использовать их промежуточное ПО для защиты некоторых маршрутов, но получаю следующее исключение:

ReflectionException in Container.php line 741:
Class App\Http\Zizaco\Entrust\Middleware\EntrustPermission does not exist

Вот содержимое моего файла composer.json:

Вот содержимое моего файла App \ Http \ Kernel.php:

<?php

namespace App\Http;

use Illuminate\Foundation\Http\Kernel as HttpKernel;

class Kernel extends HttpKernel
{

protected $middleware = [

}

И вот как я пытаюсь использовать промежуточное ПО в моем файле rout.php:

// secure admin routes
Route::group(['middleware' => 'permission:access_admin_area'], function()
{
Route::get('admin', ['as' => 'dashboard', 'uses' => 'Admin\AdminController@index']);
});

Я почти уверен, что следовал их инструкциям к письму, все это работало, пока я не попытался использовать их промежуточное программное обеспечение маршрута. Кто-нибудь знает, где я ошибся?
