Я новичок в angular 6 и пытаюсь настроить приложение с маршрутизацией, но я не могу получить контент для загрузки с помощью ng serve. Страница загружается без ошибок, но она пуста. Я не уверен, что мне не хватает, так что контент из HomeComponent будет отображаться при переходе на localhost: 4200. Спасибо!

ng test жалуется на роутер-розетку, но я считаю, что я сделал то, что он просит в файле app.module.ts.
