macOS(M3)上でPythonで画像処理を行うCLIツールであるimgpを利用しようとしたところ、以下のようにimgpのインストールに失敗してしまいました。

macOS (M3) でのビルドはサポートされていないため、Docker を使用して imgp をインストールしようとしました。インストールプロセスを以下に説明します。
(1) Dockerコンテナの起動
docker run-v $PWD:/work --rm --platform linux/amd64 -it python:3.12-slim /bin/bash
(2) ビルド用パッケージをインストール
apt update apt install build-essential zlib1g-dev libjpeg-dev
(3) imgp をインストールします
pip install imgp
(4) インストールされたバイナリを確認します
