При необходимости класс Laravel CustomServiceProvider не найден в пакете

У меня проблемы с пользовательским пакетом композитора, который я создал для работы с Laravel. Я выполнил все необходимые шаги, о которых говорили другие. Сначала потребуйте пакет, затем composer-dumpautoload -o, а затем добавьте ServiceProvider в config/app.php. Однако laravel не может найти пакет ServiceProvider. Может быть, у меня нет интервала между именами? Вот мой код ниже вместе со ссылкой на мое репозиторий на github

config / app.php

KeithRoye\Forecast\WeatherServiceProvider::class,

WeatherServiceProvider.php

 <?php

namespace KeithRoye\Forecast;

use Illuminate\Support\ServiceProvider;

class WeatherServiceProvider extends ServiceProvider

{
    /**
     * Bootstrap services.
     *
     * @return void
     */
    public function boot()
    {
        $this->loadRoutesFrom(__DIR__.'/routes/web.php');
    }
    /**
     * Register services.
     *
     * @return void
     */
    public function register()
    {
        //
    }
}
