macOS 上安装 PHP 扩展 imagick

在 macOS 上安装 Lychee 的时候遇到报错，提示我缺少 ext-imagick 扩展。

于是直接用 pecl install imagick 安装，结果报错:

ERROR: `/private/tmp/pear/temp/imagick/configure --with-php-config=/opt/homebrew/opt/php/bin/php-config --with-imagick' failed

根据报错信息 ImageMagick MagickWand API configuration program，pecl 没有找到 MagickWand 相关的配置目录，这个应该是 imagick 的底层依赖的库。

根据 brew 的提示信息，找到了 imagemagick 这个包，尝试安装:

brew install imagemagick

经过漫长的等待（挂代理会快一点），终于安装好了，再次执行 pcel install imagick，安装成功。

执行 php -m | grep imagick 果然看到 imagick 扩展了，问题解决。

$ php -m | grep imagick
imagick

本来使用 docker 会更方便一点，但本地服务我不喜欢再跑一个 docker，太费电。
