Installation funktioniert nicht unter Contao 4.13

[rike]

Hallo ihr Lieben,

ich habe Contao 4.13 neu aufgesetzt und wollte nun Isotope installieren und bekomme leider nur folgende Konsolen-Meldung - vielleicht kann mir jemand helfen und weiß wo der Fehler liegt!? Ich wäre super dankbar!

Isotope 2.7 ist noch nicht mit Contao 4.13 kompatibel. Du könntest dir vorerst die Entwicklerversion 2.8.x-dev installieren.
