¿Instalar gema therubyracer -v '0.11.4'?
Estoy casi loco de instalartherubyracer. Sé que hay muchas personas que tienen el mismo problema conmigo, y también había visto estos problemas, sin embargo, es demasiado complicado para mí porque diferentes situaciones tienen diferentes soluciones. Y de hecho, no ha habido una buena manera de resolver el problema. Mi problema es similar aestay hay undiscusión al respecto, sin embargo todavía no tenemos una conclusión.
A pesar de esto,esta es una buena pregunta hecha porChris S, pero no es un buen resultado.
① Aquí hay algunas notas sobre mi problema:
1.ruby 2.2.1p85 (2015-02-26 revisión 49769) [x86_64-darwin15]
2.libv8 3.11.8.17 con extensiones nativas
② OS X El Capitan, 10.11

¡Ayuda!
Bueno, en primer lugar siento mucho volver a editar el problema, estoy demasiado ocupado sin tiempo para notar los comentarios que sus muchachos respondieron por mí. Y, aquí, estoy muy agradecido de que @Javid Jamae me brinde una excelente manera de resolver el problema, aunque todavía hay algunos asuntos pequeños que resolver, pero está bien que solo necesitemos los errores para ayudarnos a encontrar el respuesta final. La siguiente es la consola después de haber probado @Javid Jamae way,
Primero, no he instaladogcc conelaborar cerveza antes, así que lo instalé con brew y la versión es la última5.2.0 (/usr/local/Cellar/gcc/5.2.0) Aquí están los detalles:

.................. (the follow error messages are similar to above)
Bueno, me pregunto si sigue siendo el problema delibv8! Al principio, creo que tal vez sea el problema de la versión detherubyracer, así que intenté instalar la versión0.12.0Desafortunadamente, hay los mismos errores. Hay algo extraño, quiero decir ellibv8 se instala con eltherubyracer en mi caso (mira eso de los mensajes de error), pero eres diferente conmigo. Como su sugerencia marcó, instale ellibv8 después de haber instalado eltherubyracer¿Por qué son diferentes? Tal vez se relacione con mirubí configuración del entorno, aquí publiqué miGemfile configuración:
