Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires PHP extension ext-gd * but it is missing from your system. Install or enable PHP's gd extension. Problem 2 - Root composer.json requires szymach/c-pchart ^3.0 -> satisfiable by szymach/c-pchart[v3.0.0, ..., v3.0.17]. - szymach/c-pchart v3.0.12 requires php ^5.4|^7.0|8.0.* -> your php version (8.4.13) does not satisfy that requirement. - szymach/c-pchart[v3.0.0, ..., v3.0.17] require ext-gd * -> it is missing from your system. Install or enable PHP's gd extension. To enable extensions, verify that they are enabled in your .ini files: - /usr/local/etc/php/conf.d/docker-php-ext-opcache.ini - /usr/local/etc/php/conf.d/docker-php-ext-sodium.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-gd` to temporarily ignore these required extensions.
