произошла ошибка при установке гема semacode (0.7.5)

Проблема при установке гема семакода из гемфайла. есть способ решить эту проблему? Я запускаю установку пакета. Это проблема с моей машиной или с драгоценным камнем? Эта проблема впервые возникла на моем компьютере, когда я попытался запустить приложение локально.

Использование семакода 0.7.5 из https://github.com/toretore/semacode.git ( у мастера @ 4e31e0b)
