laravel 4.2 Ошибка установки компоновщика

Question

Всякий раз, когда я пытаюсь установить композитор, я все время получаю сообщение об ошибке. Ниже я вижу на своем терминале. Я попытался опустить версию кассира. Ive пытался на другой проект laravel. Я продолжаю получать ту же ошибку, Не уверен, что происходит.
