更新1：得到mailatcher工作，但运行每个测试现在需要4分钟。
我需要在Github工作流中进行一些Mailcatcher验收测试。所有其他测试都运行良好。我也运行了Mailcatcher，但安装所有依赖项的gem需要大约4分钟（！），这是不可接受的。
有什么方法可以加快速度吗？环境是LAMP。
这就是YAML文件：

        php: ["7.4"]
    name: PHP ${{ matrix.php }} Test on ${{ matrix.operating-system }}

    env:
      php-ini-values: post_max_size=32M

    steps:
      - name: Checkout
