Laravel 5.4 npm run dev Fehler

Question

FIXED: Lösung war, den Ordner node_modules zu löschen und npm instal neu zu starten, und danach alles funktionierte.

Ich habe einige Probleme mit Laravel und zu versuchen, "npm run dev" zu laufen, bekomme ich diesen Fehler:

Meine Versionen von Npm und Knoten ist:

Npm: 4.5. 0 Knoten: V7.8.0

Und Laravel 5.4

Hier ist meine packages.json:

    },
