Ошибка при доступе к свойству symfony при установке composer

Question

Я пытаюсь установить зависимости для своего проекта, но постоянно получаю эту ошибку:

Загрузка репозиториев композитора с информацией о пакете Установка зависимостей (включая require-dev) из файла блокировки. Ваши требования не могутбыть решен в устанавливаемый набор пакетов.

Проблема 1 - Запрос установки для symfony / property-access v4.1.4 -> выполнимый с помощью symfony / property-access [v4.1.4].- не устанавливать symfony / symfony v3.4.15 | не устанавливать symfony / property-access v4.1.4 - запрос установки для symfony / symfony v3.4.15 -> выполняется symfony / symfony [v3.4.15].
