执行composer install时，经常出现you can run Composer with--ignore-platform-req=ext-fileinfoto temporarily ignore these required extensions问题，此时如何只是用composer 命令安装时，执行命令时加上--ignore-platform-req=ext-fileinfo就可以了，但是要执行php artisan breeze:install vue 等是，就不能这样修改了。
- 执行composer
简单解决：
composer install --ignore-platform-req=ext-fileinfo
2.执行php artisan xxx:install xxx时。出现以下问题。
php artisan breeze:install vue
./composer.json has been updated
Running composer update inertiajs/inertia-laravel laravel/sanctum tightenco/ziggy

Your requirements could not be resolved to an installable set of packages.
Problem 1
- league/flysystem-local 3.23.0 requires ext-fileinfo * -> it is missing from your system. Install or enable PHP's fileinfo extension.
- laravel/framework v10.40.0 requires league/flysystem ^3.8.0 -> satisfiable by league/flysystem[3.22.0].
- league/flysystem 3.22.0 requires league/flysystem-local ^3.0.0 -> satisfiable by league/flysystem-local[3.23.0].
- laravel/framework is locked to version v10.40.0 and an update of this package was not requested.
To enable extensions, verify that they are enabled in your .ini files:
- C:\phpstudy_pro\Extensions\php\php-8.3.1-Win32-vs16-x64\php.ini
You can also run `php --ini` in a terminal to see which files are used by PHP in CLI mode.
Alternatively, you can run Composer with `--ignore-platform-req=ext-fileinfo` to temporarily ignore these required extensions.
Installation failed, reverting ./composer.json and ./composer.lock to their original content.
PS
解决也很简单：在php.ini文件中，追加extension=php_fileinfo就可以了。同时，composer的问题也解决了。完整的参考配置目录如下。
