Your requirements could not be resolved to an installable set of packages. Problem 1 - phpspec/prophecy v1.17.0 requires php ^7.2 || 8.0.* || 8.1.* || 8.2.* -> your php version (8.3; overridden via config.platform, actual: 8.3.8) does not satisfy that requirement. - phpspec/prophecy-phpunit v2.0.2 requires phpspec/prophecy ^1.3 -> satisfiable by phpspec/prophecy[v1.17.0]. - phpspec/prophecy-phpunit is locked to version v2.0.2 and an update of this package was not requested.
