Quelle est ta version de Node.js ?

Exécute node -v dans un terminal stp.

Ton message d'erreur est sur la ligne > 26 | return { ...acc, ...localeObj };, or la syntaxe spread sur les litéraux n'est supportée qu'à partir de la version 8 de node.

J'ai la version 10.11

Désolé ma question était à l'ouest, il s'agit d'un front, donc exécuté dans ton navigateur mais c'est le même problème.

Apparemment tu utilises Babel en version 6 or la gestion du spread dans les littéraux n’apparaît que dans la version 7 (c'est de l'ES2018).

Il faut mettre à jour tes dépendances dev.

Peux-tu me dire les dépendences à mettre à jour stp
28/10/2018, 17h20
Marco46

Ya pas vraiment de réponse simple, il va falloir que tu cherches et que tu creuses par toi même, à mon avis tu peux déjà faire un essai en montant de version tout ce qui démarre par babel-.

La commande npm outdated devrait te lister toutes les dépendances pour lesquelles tu as du retard sur @latest.

Il fallait que j'ajoute cette dépendence également :
npm install --save-dev @babel/plugin-proposal-class-properties
