Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires PHP extension ext-exif * but it is missing from your system. Install or enable PHP's exif extension. Problem 2 - Root composer.json requires PHP extension ext-gd * but 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-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-exif --ignore-platform-req=ext-gd` to temporarily ignore these required extensions.
