L'installation du bundle install libv8 (therubyracer) échoue (avec les extensions natives) sous Windows

J'essaie de faire une installation groupée sur ma machine Windows et j'ai essayé d'inclure les deux gemmes suivantes :

gem 'therubyracer'
gem 'libv8', '3.3.10.4'

Mais aucun des deux ne semble fonctionner, ce qui me laisse avec cette erreur :

Installing libv8 (3.3.10.4) with native extensions Unfortunately, a fatal error has occurred. Please report this error to the Bun
dler issue tracker at https://github.com/carlhuda/bundler/issues so that we can fix it. Thanks!

Y a-t-il un moyen de contourner ce problème ?

Vérifiez les dépendances de la langue : https://github.com/fractaloop/libv8/graphs/languages

Vous devez installer Python sur votre machine. Une fois cela fait, j'installerais également la dernière version de bundler :

gem install bundler --pre

Assurez-vous que Python 2.7 est installé et se trouve dans votre chemin d'accès Windows.
