Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires phpunit/phpunit ^11.0 -> satisfiable by phpunit/phpunit[11.0.0, 11.0.x-dev]. - phpunit/phpunit[11.0.0, ..., 11.0.x-dev] require php >=8.2 -> your php version (7.4.6; overridden via config.platform, actual: 7.4.33) does not satisfy that requirement. Problem 2 - dibi/dibi[dev-master, v5.0.0, ..., 5.0.x-dev] require php 8.0 - 8.3 -> your php version (7.4.6; overridden via config.platform, actual: 7.4.33) does not satisfy that requirement. - dibi/dibi 5.0.x-dev is an alias of dibi/dibi dev-master and thus requires it to be installed too. - Root composer.json requires dibi/dibi ~5.0 -> satisfiable by dibi/dibi[v5.0.0, v5.0.1, 5.0.x-dev (alias of dev-master)].
