Psych :: SyntaxError non ha potuto analizzare YAML

Question

Ho riscontrato problemi nell'applicazione rails in esecuzione su Fedora 16 Rails versione 2.3.5 e Ruby 1.9.2.p320. L'applicazione funziona bene su Ubuntu 11.10. Quando eseguo il server dei binari e colpisco qualsiasi controller, il seguente errore si presenta.

Psych :: SyntaxError in NomeControllore # ActionName

Impossibile analizzare YAML

Ho provato il applicare il seguente trucco ma non è lavorare per me.

ho aggiunto la seguente riga in config/boot.rb

require 'yaml' 

YAML::ENGINE.yamler = 'syck' 

la traccia di errore è

Answer 1

parser YAML più vecchio non come avere le schede, ma solo spazi. Potresti voler controllare il tuo file YAML per vedere se ha qualche tab alla riga 18. Se questo è il caso, potresti voler correggere i tuoi file YAML o aggiornare il parser.
