Erreur lors de l’exécution du serveur RAILS sur Gitbash

Je suis nouveau sur Ruby on Rails et j’essayais de l’apprendre en utilisant les vidéos sur youtube et j’ai installé Heroku, Postgre SQL, Git Bash et essayé d’exécuter le serveur Rails et d’obtenir l’erreur suivante.

Pouvez-vous m’aider à ce sujet? Il y avait un problème similaire posté ici, j’ai essayé d’utiliser la résolution fournie ici, mais cela n’a pas fonctionné.

• Essayé de dégager le # gem 'therubyracer', platforms: :ruby qui n’a pas fonctionné

• Les gens ont mentionné que nous devions installer Nodejs bien que je dispose de nodejs dans mon système. Je ne l’utilise pas si je l’installe même si je ne vais pas l’utiliser?

  • Première utilisation du serveur Ruby – La commande ne donne aucune réponse
  • Pas de permission lors de la mise en place de rbuy sur rails
  • installation de gem puma sur Windows error
  • Comment savoir si j’utilise Puma en mode cluster?
  • Transfert de données entre deux serveurs de rails

S’il vous plaît, aidez-moi à ce sujet.
