Plugin compose install not working

[AleksandarDev]

Following this step:

Navigate to plugin folder ($ROOT/wp-content/plugins/<plugin_name>) and install composer dependencies:

composer install

I'm getting following error:

To enable extensions, verify that they are enabled in your .ini files:
    - /etc/php/8.3/cli/php.ini
    - /etc/php/8.3/cli/conf.d/10-opcache.ini
    - /etc/php/8.3/cli/conf.d/10-pdo.ini
    - /etc/php/8.3/cli/conf.d/20-calendar.ini
    - /etc/php/8.3/cli/conf.d/20-ctype.ini
    - /etc/php/8.3/cli/conf.d/20-curl.ini
    - /etc/php/8.3/cli/conf.d/20-exif.ini
    - /etc/php/8.3/cli/conf.d/20-ffi.ini

    - /etc/php/8.3/cli/conf.d/20-sysvsem.ini
    - /etc/php/8.3/cli/conf.d/20-sysvshm.ini
    - /etc/php/8.3/cli/conf.d/20-tokenizer.ini
You can also run `php --ini` in a terminal to see which files are used by PHP in CLI mode.
Alternatively, you can run Composer with `--ignore-platform-req=ext-dom` to temporarily ignore these required extensions.

System:

Ubuntu 24.04.1 LTS (GNU/Linux 5.15.133.1-microsoft-standard-WSL2 x86_64)
Composer version 2.8.1 2024-10-04 11:31:01
PHP version 8.3.6 (/usr/bin/php8.3)

This starter assumes you have set up your LEMP stack (as per README.md Requirements section). If you have some problems with Nginx, PHP, networking etc. in your environment, this should be solved separately from this project.

In your case, this error descriptively explains that you have some missing PHP extensions in your environment. Please take a look at official WP documentation about required extensions.

We are planning to prepare a Docker file which would prepare the stack in a controlled Docker container that would require you to only have a working Docker installed, apart from the whole LEMP stack.
