Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires matthiasnoback/symfony-dependency-injection-test ^4.3.1 -> satisfiable by matthiasnoback/symfony-dependency-injection-test[v4.3.1]. - matthiasnoback/symfony-dependency-injection-test v4.3.1 requires symfony/dependency-injection ^4.4 || ^5.3 || ^6.0 -> found symfony/dependency-injection[v4.4.0-BETA1, ..., 4.4.x-dev, v5.3.0-BETA1, ..., 5.4.x-dev, v6.0.0-BETA1, ..., 6.4.x-dev] but these were not loaded, likely because it conflicts with another require.
