Traté de desinstalar rvm para usar rbenv en mi Mac. Todo funciona bien hasta que el rubí entra en juego.

cuando usas

<code>rbenv install 1.9.3-p194
</code>

lo compila correctamente, pero después de eso me gustaría instalar el empaquetador ... esto produce el siguiente error

<code>computer:~ computer$ gem install bundler

    from /Users/computer/.rbenv/versions/1.9.3-p194/bin/gem:21:in `<main>'
</code>

Luego intenté instalar una versión anterior de ruby ​​1.9.3-p125 ... pero incluso la compilación no terminará con un error similar que también depende de este intérprete psíquico ... :(

No pude encontrar algo en la red que tuviera los mismos problemas, así que pregunto ...

Probé esos dos recursos que no me ayudaron como si el instalador de rbenv estuviera haciendo esto automáticamente

Instalando libyaml para ruby ​​en un mac osX (Lion)

¿Reparando el error "falta la instalación de ruby ​​psych"?

¿Alguien tiene alguna sugerencia? Gracias por adelantado..
