Alles war fein gearbeitet, bis ich an meinem Projekt geprüft ein anderer Computer. Nach der Installation der Abhängigkeiten mit

Gibt es jemanden, der wissen würde, was hier vor sich geht?

Answer 1

Es scheint ein Problem mit Webpack 2.2.0 oder einer seiner Abhängigkeiten zu sein. Wenn Sie "webpack": "^2.1.0-beta.25" durch "webpack": "2.2.0-rc.3" ersetzen, wird es wieder funktionieren. rc.4 ist der Punkt es brach
