Als ich versuchte, imgp zu verwenden, ein CLI-Tool für die Bildverarbeitung in Python unter macOS (M3), schlug die Installation von imgp wie folgt fehl.

Building auf macOS (M3) wird nicht unterstützt, daher habe ich versucht, imgp mit Docker zu installieren. Der Installationsprozess wird unten beschrieben.
(1) Docker-Container starten
docker run-v $PWD:/work --rm --platform linux/amd64 -it python:3.12-slim /bin/bash
(2) Pakete zum Erstellen installieren
apt update apt install build-essential zlib1g-dev libjpeg-dev
(3) Installieren Sie imgp
pip install imgp
(4) Überprüfen Sie die installierte Binärdatei
