Only one of these can be installed: illuminate/contracts[dev-master, v5.1.1, ..., 5.8.x-dev, v6.0.0, ..., 6.x-dev, v7.0.0, ..., 7.x-dev, v8.0.0, ..., 8.x-dev, v9.0.0-beta.1, ..., 9.x-dev, v10.0.0, ..., 10.x-dev, v11.0.0, ..., 11.x-dev], laravel/framework[v11.0.0, ..., 11.x-dev]. laravel/framework replaces illuminate/contracts and thus cannot coexist with it.
