composer require overtrue/laravel-lang 报错

通过安装 overtrue/laravel-lang 这个扩展包可以直接把语言变成中文：

composer require overtrue/laravel-lang

然后再服务器运行代码之后报错

Problem 1
    - laravel/framework is locked to version v8.83.29 and an update of this package was not requested.
    - laravel/framework v8.83.29 requires tijsverkoyen/css-to-inline-styles ^2.2.2 -> satisfiable by tijsverkoyen/css-to-inline-styles[v2.3.0].
    - symfony/css-selector v7.2.0 requires php >=8.2 -> your php version (8.1.32) does not satisfy that requirement.
    - tijsverkoyen/css-to-inline-styles v2.3.0 requires symfony/css-selector ^5.4 || ^6.0 || ^7.0 -> satisfiable by symfony/css-selector[v7.2.0].

You can also try re-running composer require with an explicit version constraint, e.g. "composer require overtrue/laravel-lang:*" to figure out if any version is installable, or "composer require overtrue/laravel-lang:^2.1" if you know which you need.

Installation failed, reverting ./composer.json and ./composer.lock to their original content.

根据错误信息，问题是由于依赖的 symfony/css-selector 版本过高（需要 PHP 8.2）导致的。以下是解决方案：

方法 1：降级 symfony/css-selector 到兼容版本 手动指定版本：在 composer.json 中添加版本约束，限制 symfony/css-selector 使用 6.x 系列：

composer require symfony/css-selector:^6.0

运行结果
