Psych :: SyntaxError no pudo analizar YAML

Question

Estoy enfrentando un problema en la aplicación de rieles que se ejecuta en fedora 16 Rails versión 2.3.5 y Ruby 1.9.2.p320. La aplicación funciona bien en Ubuntu 11.10. Cuando ejecuto el servidor de rieles y golpeo cualquier controlador, aparece el siguiente error.

Psych :: SyntaxError en controllername # actionname

no pudo analizar YAML

He probado la aplicación lo siguiente truco, pero no es un trabajo para mí.

he añadido la línea siguiente en config/boot.rb

require 'yaml' 

YAML::ENGINE.yamler = 'syck' 

la traza de error es

Answer 1
