Chicos, estoy a punto de suicidarme con este!

Tuve algunos problemas con RVM al instalar varias versiones de Ruby, y siguiendo un hilo en Stackoverflow, decidí eliminarlo por completo. Después de reinstalar RVM, no puedo instalar ninguna versión de Ruby.

Mac OS XRVM 1.20.10 estableHomebrew 0.9.4

Aquí hay algunos registros:

rvm instalar 2.0.0-p0

o:

rvm install 2.0.0-p195 --autolibs = habilitado
