Je suis en cours d'exécution sur le système d'exploitation Windows Vista 64 bits. Geografikos est un grand projet créé en tant que projet de thèse de maîtrise par Jeremy Witmer. Tout est codé dans JRuby. Je suis en train d'élargir le projet sous sa direction mais je ne peux pas exécuter son programme. Les pierres précieuses suivantes ont été installées:Jruby LoadError: Impossible d'ouvrir l'un des fichiers [xml2, xslt, exslt] WINDOWS
