Bonjour j'ai un probleme avec le npm start de react native. je suis débutant dans ce domaine. je suis entrain de suivre le cours sur le développement d'appli mobile avec react native. mon probleme est que quand je lance la comande "npm start" j'obtiens des érreurs et du coup ça marche pas. j'espere que quelqu'un pourra m'aider. voila ce que j'obtiens quand je lance la commande.

PS C:\Users\lenovo\Desktop\concours\moviesandme> npm start

> @ start C:\Users\lenovo\Desktop\concours\moviesandme
> expo start
