我在使用composer安装Laravel 11的时候，遇到如下错误：
Your requirements could not be resolved to an installable set of packages.
Problem 1
- laravel/framework[v11.9.0, ..., v11.23.3] require fruitcake/php-cors ^1.3 -> found fruitcake/php-cors[dev-feat-setOptions, dev-master, dev-main, dev-test-8.2, v0.1.0, v0.1.1, v0.1.2, v1.0-alpha1, ..., 1.2.x-dev (alias of dev-master)] but it does not match the constraint.
- Root composer.json requires laravel/framework ^11.9 -> satisfiable by laravel/framework[v11.9.0, ..., v11.23.3].原因是阿里云composer镜像源中没有fruitcake/php-cors包的最新版。
解决方法是，切换回默认的composer镜像源：
composer config -g --unset repos.packagist执行composer install就安装成功了，不再报错。
