Your requirements could not be resolved to an installable set of packages. Problem 1 - Only one of these can be installed: symfony/symfony[v7.0.0, v7.0.1], symfony/config[v5.4.0, ..., v5.4.31, v6.0.0, ..., v6.4.0, v7.0.0]. symfony/symfony replaces symfony/config and thus cannot coexist with it. - matthiasnoback/symfony-dependency-injection-test 4.3.0 requires symfony/config ^4.4 || ^5.3 || ^6.0 -> satisfiable by symfony/config[v5.4.0, ..., v5.4.31, v6.0.0, ..., v6.4.0]. - Conclusion: don't install symfony/config v6.0.19 (conflict analysis result) - Conclusion: don't install symfony/config v6.2.13 (conflict analysis result) - Conclusion: don't install symfony/config v6.3.8 (conflict analysis result) - Conclusion: don't install symfony/config v6.4.0 (conflict analysis result) - Root composer.json requires matthiasnoback/symfony-dependency-injection-test 4.3.0 -> satisfiable by matthiasnoback/symfony-dependency-injection-test[4.3.0]. - Root composer.json requires symfony/symfony 7.0.* -> satisfiable by symfony/symfony[v7.0.0, v7.0.1].
