Bonjour
Quand je veux créer un projet avec la commande "ng new mon-projet" je reçois les erreurs suivantes:

npm WARN deprecated fsevents@1.2.9: One of your dependencies needs to upgrade to fsevents v2: 1) Proper nodejs v10+ support 2) No more fetching binaries from AWS, smaller package size

Comment puis-je corriger ce problème??

Merci
