【问题描述】：

尝试为 php 8.1.1 安装 imagick。

在composer install 下方我的Dockerfile 的图像上出现以下错误：

Installing dependencies from lock file (including require-dev)
Verifying lock file contents can be installed on current platform.
Your lock file does not contain a compatible set of packages. Please run composer update.

  Problem 1
    - Root composer.json requires PHP extension ext-imagick ^3.6 but it is missing from your system. Install or enable PHP's imagick extension.

To enable extensions, verify that they are enabled in your .ini files:
    - 
    - /usr/local/etc/php/conf.d/docker-php-ext-apcu.ini
    - /usr/local/etc/php/conf.d/docker-php-ext-calendar.ini
    - /usr/local/etc/php/conf.d/docker-php-ext-gd.ini
    - /usr/local/etc/php/conf.d/docker-php-ext-intl.ini
    - /usr/local/etc/php/conf.d/docker-php-ext-opcache.ini
    - /usr/local/etc/php/conf.d/docker-php-ext-pdo_mysql.ini
    - /usr/local/etc/php/conf.d/docker-php-ext-pdo_pgsql.ini
    - /usr/local/etc/php/conf.d/docker-php-ext-sodium.ini
    - /usr/local/etc/php/conf.d/docker-php-ext-xsl.ini
    - /usr/local/etc/php/conf.d/docker-php-ext-zip.ini

我尝试了各种解决方案

apt install php-imagick 给出错误：

Package php-imagick is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source

apt install php8.1-imagick 没有找到任何包

在我的Dockerfile末尾添加RUN docker-php-ext-install php-imagick或RUN docker-php-ext-install imagick找不到任何包

【问题讨论】：

为什么不按照您已经安装的其他扩展程序的方式安装它？
这样我以后可以把它分解成子图像

标签： php docker imagick

【解决方案1】：

RUN apt-get update; \
    # Imagick extension
    apt-get install -y libmagickwand-dev; \
    pecl install imagick; \
    docker-php-ext-enable imagick; \
    # Success
    true
