Création de ma première application - échec de yarn create

Bonjour,

J’essaye de développer ma première application en suivant le tuto https://docs.cozy.io/en/tutorials/app/ mais la commande “yarn create cozy-app myapp” échoue. J’ai cherché mais je ne réussis pas du tout à voir d’où vient le problème.

Voici ce que m’affiche la commande :

yarn create v1.22.4

Je suis nouveau sur yarn et je dois dire que là je ne vois pas du tout comment débuger ça. Surtout que je ne vois pas dans les log d’où vient l’erreur.

Est-ce que queulqu’un pourrait m’aider ?

Merci !
