Installation de l'erreur Rails 12.04

J'ai suivi tous les étapes de cette page https://www.digitalocean.com/community/articles/how-to-install-Ruby-on-Rails-on-ubuntu-12-04-lts-precise- pangolin-with-rvm

Tout se passe bien jusqu'à la commande d'installer Rails

gem install Rails

Je reçois cette erreur:

ERROR:  While executing gem ... (Gem::RemoteFetcher::UnknownHostError)
    no such name (http://api.rubygems.org/api/v1/dependencies?gems=activerecord-deprecated_finders)

ON chaque nouveau message d'erreur try indique différentes dépendances de gemmes? Gems = .......

Des conseils sur ce problème?

Voici la trace de pile complète après l'exécution de coomand gem install Rails -V

J'ai installé Rails la semaine dernière en suivant les instructions ci-dessous:

http://railsapps.github.io/installrubyonrails-ubuntu.html

Les différences notables entre les procédures sont:

l'ajout du --Ruby à la commande:

\curl -L https://get.rvm.io | bash -s stable --Ruby

La commande pour mettre à jour RVM est à la place:

rvm get stable --autolibs=enable

La version de Ruby à utiliser est explicitement définie:

rvm --default use Ruby-2.1.0

Installation de js.Node

Sudo apt-get install nodejs

L'installation de Rails est également précédée par la définition explicite de la version:

rvm use [email protected] --create
