Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires symfony/maker-bundle * -> satisfiable by symfony/maker-bundle[1.0.0, ..., v1.61.0]. - symfony/maker-bundle[1.0.0, ..., v1.22.0] require php ^7.1.3 -> your php version (8.0.99; overridden via config.platform, actual: 8.1.2) does not satisfy that requirement. - symfony/maker-bundle[v1.0.1, ..., v1.16.0] require php ^7.0.8 -> your php version (8.0.99; overridden via config.platform, actual: 8.1.2) does not satisfy that requirement. - symfony/maker-bundle[v1.23.0, ..., v1.33.0] require nikic/php-parser ^4.0 -> found nikic/php-parser[v4.0.0, ..., v4.19.4] but the package is fixed to v5.3.1 (lock file version) by a partial update and that version does not match. Make sure you list it as an argument for the update command. - symfony/maker-bundle[v1.34.0, ..., v1.50.0] require nikic/php-parser ^4.11 -> found nikic/php-parser[v4.11.0, ..., v4.19.4] but the package is fixed to v5.3.1 (lock file version) by a partial update and that version does not match. Make sure you list it as an argument for the update command. - symfony/maker-bundle[v1.51.0, ..., v1.61.0] require php >=8.1 -> your php version (8.0.99; overridden via config.platform, actual: 8.1.2) does not satisfy that requirement. Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.
