I used composer to upgrade to Laravel 5.3, which broke it

Question

Here's the exception I get now when I try to run my page. I've tried removing and recreating the bootstrap/cache based on some recommendations I've seen online. I've tried removing the arguments in the ServiceProvider files for the boot method. Nothing works.

ErrorException in EventServiceProvider.php line 9:

Also, when I run "composer update", I get this exception:

You need to remove the arguments from RouteServiceProvider and EventServiceProvider.

From the upgrade guide:

You may remove the arguments from the boot method on the EventServiceProvider, RouteServiceProvider, and AuthServiceProvider classes. Any calls to the given arguments may be converted to use the equivalent facade instead. So, for example, instead of calling methods on the $dispatcher argument, you may simply call the Event facade. Likewise, instead of making method calls to the $router argument, you may make calls to the Route facade, and instead of making method calls to the $gate argument, you may make calls to the Gate facade.

Laravel 5.2 EventServiceProvider example:

namespace App\Providers;

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',
        ],
    ];

    /**
     * Register any other events for your application.
     *
     * @param  \Illuminate\Contracts\Events\Dispatcher  $events
     * @return void
     */
    public function boot(DispatcherContract $events)
    {
        parent::boot($events);

        //
    }
}

Laravel 5.3 EventServiceProvider example:

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 events for your application.
     *
     * @return void
     */
    public function boot()
    {
        parent::boot();

        //
    }
}
