Сложность установки therubyracer 0.10.2 и apple-gcc42 на Mac OSX 10.12.6 Sierra

Ответ на этот похожий вопрос не решает мою проблему. Вот ответ на этот вопрос:

Если вы решите использовать новую версию gem-версии therubyracer, вы не будете дольше эта проблема

В противном случае:
brew tap homebrew/dupes # Thanks Tom
brew install apple-gcc42

export CC=/usr/local/Cellar/apple-gcc42/4.2.1-5666.3/bin/gcc-4.2
export CXX=/usr/local/Cellar/apple-gcc42/4.2.1-5666.3/bin/g++-4.2
export CPP=/usr/local/Cellar/apple-gcc42/4.2.1-5666.3/bin/cpp-4.2

brew uninstall v8

gem uninstall libv8

gem install therubyracer -v '0.10.2' # specify version

Проблема, с которой я сталкиваюсь с этим решением, - apple-gcc42. Когда я запустил эту строку:

brew install apple-gcc42

Я получаю следующую ошибку:

apple-gcc42: This formula either does not compile or function as expected on macOS
versions newer than Mavericks due to an upstream incompatibility.

Если я проигнорирую эту ошибку и попробую gem install therubyracer -v '0.10.2', я получаю следующее:

Я пробовал много других решений, таких как другие ответы на связанный вопрос, но большинство из них полагаются на apple-gcc42.
