Your lock file does not contain a compatible set of packages. Please run composer update. Problem 1 - Root composer.json requires PHP extension ext-zip * but it is missing from your system. Install or enable PHP's zip extension. Problem 2 - box/spout is locked to version v3.3.0 and an update of this package was not requested. - box/spout v3.3.0 requires ext-zip * -> it is missing from your system. Install or enable PHP's zip 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-zip` to temporarily ignore these required extensions.
