Soweit ich das beurteilen kann, scheint es, dass das NPM-Paket installiert wird, also warum kann das Modul nicht gefunden werden? Ich bin ziemlich neu in React (ich bin der Backend-Entwickler bei diesem Projekt), jede Hilfe wird geschätzt.

Answer 1

Aus der ersten Zeile in Ihrem Protokoll: npm install --only=dev sieht es aus wie Sie sind nur ziehen devDependencies. chart.js ist in dependencies registriert, so dass --only=devchart.js nicht herunterladen wird.

Um über den --only Schalter zu lesen, here is the documentation.

Ich würde vorschlagen, dass Sie die --only Flagge aus dem npm install wenn möglich entfernen.
