Class 'BaseController' not found in 'RouteController.php'

Начал писать сайт и столкнулся с такой проблемой. Создал RouteController, который служит за разбор адресной строки и создал наследуемый класс, чтобы была связка:

protected $controller;
protected $inputMethod;
protected $outputMethod;
protected $parameters;

Ну в общем говоря базовый класс,который наследуется RouteController'ом. Но когда я только добавил к "class RouteController" "extends BaseController", он у меня сразу начал ругаться и выводил такую ошибку: PHP Fatal error: Uncaught Error: Class 'Core\Base\Controllers\BaseController' not found in /var/www/Artemiys_Shop/Core/Base/Controllers/RouteController.php:10 Stack trace: #0 {main} thrown in /var/www/Artemiys_Shop/Core/Base/Controllers/RouteController.php on line 10

Может кто знает, где я может быть ошибся или делаю не так? Раньше как то с таким не возникали проблемы.
