我使用composer升级到Laravel 5.3，这打破了它

这是我尝试运行页面时遇到的异常。我尝试根据我在网上看到的一些建议删除并重新创建引导程序/缓存。我尝试删除 ServiceProvider 文件中启动方法的参数。什么都不起作用。

另外，当我运行“composer update”时，出现以下异常：

事件服务提供者.php

<?php

namespace App\Providers;

use Illuminate\Support\Facades\Event;
use Illuminate\Foundation\Support\Providers\EventServiceProvider as ServiceProvider;

class EventServiceProvider extends ServiceProvider
{
    /**
     * The event listener mappings for the application.
     *
     * @var array
     */
    protected $listen = [
        'App\Events\SomeEvent' => [
            'App\Listeners\EventListener',
        ],
    ];

    /**
     * Register any other events for your application.
     *

     * @return void
     */
    public function boot()
    {
        parent::boot();

        //
    }
}

路由服务提供商.php

<?php

namespace App\Providers;

use Illuminate\Support\Facades\Route;
use Illuminate\Routing\Router;
use Illuminate\Foundation\Support\Providers\RouteServiceProvider as ServiceProvider;

class RouteServiceProvider extends ServiceProvider
{
    /**
     * This namespace is applied to your controller routes.
     *
     * In addition, it is set as the URL generator's root namespace.
     *
     * @var string
     */
    protected $namespace = 'App\Http\Controllers';

    /**
     * Define your route model bindings, pattern filters, etc.
     *

     * @return void
     */
    public function boot()
    {
        //

        parent::boot();
    }

    /**
     * Define the routes for the application.
     *
     * @param  \Illuminate\Routing\Router  $router
     * @return void
     */
    public function map(Router $router)
    {
        $this->mapWebRoutes($router);

        //
    }

    /**
     * Define the "web" routes for the application.
     *
     * These routes all receive session state, CSRF protection, etc.
     *
     * @param  \Illuminate\Routing\Router  $router
     * @return void
     */
    protected function mapWebRoutes(Router $router)
    {
        $router->group([
            'namespace' => $this->namespace, 'middleware' => 'web',
        ], function ($router) {
            require app_path('Http/routes.php');
        });
    }
}

AuthServiceProvider.php

<?php

namespace App\Providers;

use Illuminate\Support\Facades\Gate;
use Illuminate\Foundation\Support\Providers\AuthServiceProvider as ServiceProvider;

class AuthServiceProvider extends ServiceProvider
{
    /**
     * The policy mappings for the application.
     *
     * @var array
     */
    protected $policies = [
        'App\Model' => 'App\Policies\ModelPolicy',
    ];

    /**
     * Register any application authentication / authorization services.
     *

     * @return void
     */
    public function boot()
    {
        $this->registerPolicies();

        //
    }
}

您需要从中删除参数RouteServiceProvider and EventServiceProvider.

来自升级指南 https://laravel.com/docs/5.3/upgrade#upgrade-5.3.0:

您可以从 EventServiceProvider、RouteServiceProvider 和 AuthServiceProvider 类的 boot 方法中删除参数。对给定参数的任何调用都可以转换为使用等效的外观。因此，例如，您可以简单地调用事件外观，而不是调用 $dispatcher 参数上的方法。同样，您可以调用 Route 外观，而不是对 $router 参数进行方法调用，并且您可以调用 Gate 外观，而不是对 $gate 参数进行方法调用。

use Illuminate\Contracts\Events\Dispatcher as DispatcherContract;
use Illuminate\Foundation\Support\Providers\EventServiceProvider as ServiceProvider;

class EventServiceProvider extends ServiceProvider
{
    /**
     * The event listener mappings for the application.
     *
     * @var array
     */
    protected $listen = [
        'App\Events\SomeEvent' => [
            'App\Listeners\EventListener',

    ];

    /**

    public function boot(DispatcherContract $events)
    {
        parent::boot($events);
