Установите therubyracer на OSX

Question

У меня есть новая установка ruby ​​2.1.1, чистый набор драгоценных камней, и я переустановил V8 с помощью доморощенного, но получаю эту ошибку «непризнанной командной строки».

Answer 1

мне пришлось бежать заваривания GCC обновления.

brew upgrade gcc 
==> Upgrading 1 outdated package, with result: 
gcc 4.9.1 
==> Upgrading gcc 
==> Downloading https://downloads.sf.net/project/machomebrew/Bottles/gcc-4.9.1.mavericks.bottle.2.tar.gz 
######################################################################## 100.0% 
==> Pouring gcc-4.9.1.mavericks.bottle.2.tar.gz 
==> Caveats 
GCC has been built with multilib support. Notably, OpenMP may not work: 
    https://gcc.gnu.org/bugzilla/show_bug.cgi?id=60670 
If you need OpenMP support you may want to 
    brew reinstall gcc --without-multilib

Answer 2

Изменение символической ссылки g ++ и gcc для меня работало на Mac OS 10.10.

ls -al /opt/local/bin/gcc 
ls -al /opt/local/bin/g++ 
sudo rm /opt/local/bin/gcc 
sudo rm /opt/local/bin/g++ 
sudo ln -s /usr/bin/llvm-gcc /opt/local/bin/gcc 
sudo ln -s /usr/bin/llvm-g++ /opt/local/bin/g++ 
gem install therubyracer -v '0.12.1' 
sudo rm /opt/local/bin/g++ 
sudo rm /opt/local/bin/gcc 
sudo ln -s /opt/local/bin/g++-mp-4.9 /opt/local/bin/g++ 
sudo ln -s /opt/local/bin/gcc-mp-4.9 /opt/local/bin/gcc
