Premier projet avec NetBeans - Echec de création de l'instance JRuby

J'essaie d'apprendre Ruby on Rails pour installer NetBeans sur mon Mac. J'utilise un didacticiel standard pour écrire une application de blog et suivre les instructions parfaitement. Cependant, lorsque je clique sur « Exécuter », je reçois l'erreur suivante:Premier projet avec NetBeans - Echec de création de l'instance JRuby

Oh une chose à mentionner est que je utilise Postgres et pas MySql, parce que je l'aime bien mieux. Cependant, je pense que c'est un problème de serveur Web et rien à voir avec la base de données. –

Ceci est totalement hors sujet, mais vous devez savoir que l'utilisation de RoR avec Netbeans ne sera pas une bonne idée puisque Oracle [va supprimer le support RoR dans Netbeans 7.0] (http://www.h-online.com/open/ news/item/Oracle-tire-Ruby-sur-Rails-support-from-NetBeans-7-0-1179113.html). – darioo

Oh vraiment? Y a-t-il un meilleur environnement de développement à utiliser? NetBeans était juste le premier qui m'a été recommandé, et je veux un IDE complet avec l'achèvement du code et le débogage. –

Je ne l'ai pas entendu une seule personne disent jamais qu'ils ont utilisé Glassfish pour Rails, mais ce lien a une solution pour votre erreur qui fonctionne apparemment pour certaines personnes:

Trop compliqué, s'ils ne peuvent pas être dérangés pour faire fonctionner leur programme alors ce n'est pas mon problème. Je viens d'installer RubyMine et cela fonctionne 100 fois mieux que NetBeans. –

Eh bien, j'aurais pu vous le dire aussi! Et la rubymine est bon marché pendant quelques semaines afin d'attirer les utilisateurs de Netbeans fuyant. – srboisvert
