Your lock file does not contain a compatible set of packages. Please run composer update. Problem 1 - symfony/redis-messenger is locked to version v6.4.2 and an update of this package was not requested. - symfony/redis-messenger v6.4.2 requires ext-redis * -> it is missing from your system. Install or enable PHP's redis extension. To enable extensions, verify that they are enabled in your .ini files: - /usr/local/etc/php/php-cli.ini - /usr/local/etc/php/conf.d/docker-php-ext-bz2.ini - /usr/local/etc/php/conf.d/docker-php-ext-sodium.ini - /usr/local/etc/php/conf.d/docker-php-ext-zip.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-redis` to temporarily ignore these required extensions.
