Installation Shopware 6 MAMP

Eingesetztes Betriebssystem: MAC OS 10.11.6
MAMP
PHP Version : 7.2.16
Mysql Version: 5.7.26
Node:  v12.13.1
Npm: 6.12.1

Ich bin vorgegangen wie unter https://docs.shopware.com/en/shopware-platform-dev-en/getting-started/system-installation-guides/mac-os-x beschrieben.
Beim bin/setup erhalte ich dann folgende Fehler beim Schritt 28/40

Hab schon unterschiedliche Versionen (Node, NPM, PHP) ausprobiert ohne erfolg.

Bei ./psh.phar install kommt auch der gleiche Fehler.

Die Prozedur stoppt nicht sondern quittiert dies mit Erfolg.
Das Frontend kann aufgerufen werden, nur die Administration nicht.
Hierbei fehlt unter development/public/bundles der Ordner administration und deren Unterordner.

Für Lösungsansätze wäre ich sehr dankbar
