Проблемы с установкой генератора Yeoman

Как и у многих, у меня также возникают проблемы с установкой генератора Yeoman. Я просмотрел множество примеров в Stackoverflow и попробовал несколько собственных решений, но не смог заставить их работать. Любая помощь, которую я мог бы получить для решения этой проблемы, была бы очень признательна. Я попытался установить yo angularfire и sudo angularfire.

Спасибо.

Вот мой список ошибок:
