Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires redaxo/php-cs-fixer-config ^2.0, found redaxo/php-cs-fixer-config[2.0.0, ..., 2.10.0] but the package is fixed to 1.0.0 (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. Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.

Process completed with exit code 2.
