我在下载翼手龙面板时遇到问题：当我使用命令composer compose --no-dev --optimize-autoloader启动“错误下载翼手龙”命令时 我有一个错误，是：

Do not run Composer as root/super user! See https://getcomposer.org/root for details
Loading composer repositories with package information
Installing dependencies from lock file
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Installation request for s1lentium/iptools v1.1.1 -> satisfiable by s1lentium/iptools[v1.1.1].
    - s1lentium/iptools v1.1.1 requires ext-bcmath * -> the requested PHP extension bcmath is missing from your system.

  To enable extensions,verify that they are enabled in your .ini files:

    - /etc/php/7.4/cli/conf.d/20-zip.ini
  You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.

运行php --ini时，我检查了所有内容：

我没有找到s1lentium / iptools v1.1.1的安装。 我已经找了很长时间，但是找不到任何帮助。
