Установка therubyracer 0.12.2 с собственными расширениями - Gem :: Ext :: BuildError: ОШИБКА: не удалось построить собственное расширение gem

Question

При установке therubyracer 0.12.2 с собственными расширениями я получаю сообщение об ошибке:

Gem :: Ext :: BuildError: ОШИБКА: не удалось создать собственное расширение gem

Я перепробовал все способы, такие как удаление libv8 и установка therubyracer. У меня ничего не получалось.

Команда и вывод:

>$ sudo gem install therubyracer -v '0.12.2' --source 'http://rubygems.org/'
