Adding php-imagick extension to Alpine Docker container fails

[4d4ch4u32]

I try to add the imagick php extension to my Docker container:

FROM php:8.3-fpm-alpine AS base

RUN apk add --update --no-cache --virtual .build-deps $PHPIZE_DEPS imagemagick imagemagick-dev \
    && pecl install imagick \
    && docker-php-ext-enable imagick \
    &&  rm -rf /tmp/pear \
    && apk del .build-deps

The process fails with the following error:

14.37 PHP-Parser-5.0.0/phpstan.neon.dist
14.38 Saved /tmp/pear/temp/imagick/ImagickPixel_arginfo.h
