У меня возникли проблемы с установкой Ruby с помощью RVM, и это меня озадачило. Я работаю на OS Mavericks с последними инструментами командной строки XCode и xcode. У меня есть (насколько мне известно) идентичные настройки на другой машине без проблем.

RVM появился для установки без проблем.

При попытке установить rvm 2.1 я получил следующее сообщение об ошибке:

Моей первой мыслью было запустить требования RVM, что привело к другому сообщению об ошибке

Я последовал этому совету и часами смотрел в Интернете, но пока решение для меня не сработало. Любые мысли и идеи всегда приветствуются - это меня озадачило.
