¿Por qué Middleman no incluirá las gemas rb-inotify y therubyracer una vez instaladas?

Esta es la línea a la que debes prestar atención
/home/blt/.rvm/gems/ruby-1.9.2-p290/gems/execjs-1.2.9/lib/execjs/runtimes.rb:47:in `autodetect '': no se pudo encontrar el tiempo de ejecución de JavaScript. Consulte https://github.com/sstephenson/execjs para obtener una lista de tiempos de ejecución disponibles. (ExecJS :: RuntimeUnavailable)
Básicamente, necesita instalar un tiempo de ejecución js como el nodo js o v8 o algo así en su sistema para que los ejecutivos puedan trabajar con él. Lea esto cuidadosamente

a pesar de eso:
$ gem list | grep racer therubyracer (0.9.8) $ gem list | grep inotify rb-inotify (0.8.8)
Seguí la Guía de instalación RVM y el Middleman Getting Started . ¿Alguna idea de por qué Middleman no podría iniciar un servidor?
Parece que los usuarios de middleman server un sandbox basado únicamente en el Gemfile. Si instaló las gemas globalmente, no estarán presentes en el tiempo de ejecución en el entorno limitado. El Gemfile original creado por middleman init ve así:
source "http://rubygems.org"
gem "middleman", "~>2.0.13.1"
editar esto para ser:
source "http://rubygems.org"
gem "middleman", "~>2.0.13.1"
gem "rb-inotify"
gem "therubyracer"
Podría ser menos vago y parametrizar esto por el sistema operativo, si lo desea.
Si elimina el archivo Gemfile.lock y luego ejecuta en su directorio raíz
paquete de instalación --binstubs ./bin - proveedor de ruta / paquete
el paquete instalará todos los paquetes localmente (y todos los ejecutables para iniciar cosas en ./bin)
