Я работаю над проектом Angular, который не использует и пока не может использовать Angular CLI. Поэтому я пытаюсь настроить конфигурацию Karma, но получаю эту ошибку:

Я понятия не имею, почему это происходит сейчас. У меня явно есть пусковые установки в качестве плагинов. Я беру полифилл babel как первый файл, и все же ошибка говорит мне, что у меня нет пусковых установок (запускает браузеры в любом случае), а затем вылетает с этой ошибкой из-за отсутствия полизаполнения. Почему тесты также дают ошибку при выполнении 0 из 0 Я также в растерянности Кто-нибудь знает проблему, пожалуйста?
