Hallo,

gibt es für folgende Meldung etwas, was man in die composer.json eintragen kann, das es funktioniert?

Contao 4.x-dev ist nicht kompatibel mit dem Contao Manager; bitte aktualisiere deine Installation manuell.

Code:
{
    "require": {
            "contao/calendar-bundle": "4.x-dev",
            "contao/comments-bundle": "4.x-dev",

    },
    "minimum-stability": "dev",
