Rails commande du serveur Erreur d'exécution de JavaScript

Je viens de commencer à apprendre Ruby sur les rails et tout fonctionne bien jusqu'à ce que quand je exécuter le serveur j'ai également réinstallé Nodejs et pas de verrou. je suis sur Windows 10. aussi j'ai essayé: gem update, bundle install, gem bundle install. J'ai exécuté toutes les commandes sur Git bash.Rails commande du serveur Erreur d'exécution de JavaScript
