Your requirements could not be resolved to an installable set of packages.
Problem 1
- symfony/panther[v1.1.0, ..., v1.1.1] require symfony/deprecation-contracts ^2.4 -> found symfony/deprecation-contracts[v2.4.0] but the package is fixed to v2.2.0 (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.
- Root composer.json requires symfony/panther ^1.1 -> satisfiable by symfony/panther[v1.1.0, v1.1.1].
Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.
Installation failed, reverting ./composer.json and ./composer.lock to their original content.
symfony/deprecation-contractsのバージョンが2.4以上必要だけど、2.2.0になっているよ。って見えます。
