我有一个laravel项目，我必须工作。该项目运行在laravel 8，PHP版本7.x。我使用XAMPP作为服务器，我的笔记本电脑使用windows 11，我使用PHPstorm与本地终端。当我想使用composer update，或composer install时，我得到以下错误：

Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - league/flysystem[1.1.0, ..., 1.1.10] require ext-fileinfo * -> it is missing from your system. Install or enable PHP's fileinfo extension.
    - Root composer.json requires dyrynda/laravel-cascade-soft-deletes ^4.1 -> satisfiable by dyrynda/laravel-cascade-soft-deletes[4.1.0, ..., 4.3.0].
    - laravel/framework[v8.11.0, ..., v8.83.27] require league/flysystem ^1.1 -> satisfiable by league/flysystem[1.1.0, ..., 1.1.10].
    - Root composer.json requires klips/dingoquerymapper 5.7 -> satisfiable by klips/dingoquerymapper[5.7].
    - klips/dingoquerymapper 5.7 requires laravel/framework >=5.7 -> satisfiable by laravel/framework[v8.0.0, ..., v8.83.27].
    - Only one of these can be installed: illuminate/events[v8.12.0, ..., v8.83.27, v9.0.0, ..., v9.52.4, v10.0.0, ..., v10.3.3], laravel/framework[v8.0.0, ..., v8.83.27]. laravel/framework replaces illuminate/events and thus cannot coexist with it.
    - Conclusion: install illuminate/events v8.83.27 (conflict analysis result)

To enable extensions, verify that they are enabled in your .ini files:
    - C:\Program Files\php-7.4.33-Win32-vc15-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.

Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.

我已经在网上找到了要在我的php.ini文件中取消注解的信息，行扩展名=fileinfo。我在我的php文件夹中有2个文件：ini-development和php.ini-production。问题是，在记事本中打开这两个文件后，我无法保护文件。我得到错误enter image description here
当我想使用artisan时，我得到以下错误：

PHP Fatal error:  Uncaught Error: Class 'Illuminate\Foundation\Application' not found in D:\Uni\BA\eSano\aas2-backend\src\bootstrap\app.php:14
Stack trace:
#0 D:\Uni\BA\eSano\aas2-backend\src\artisan(18): require_once()
#1 {main}
  thrown in D:\Uni\BA\eSano\aas2-backend\src\bootstrap\app.php on line 14

有什么是我错过了吗？我已经通过了所有的Stackoverflow问题是类似的，我不能解决我的问题还没有
任何帮助都将感激不尽。谢谢
我已经去窗口设置，并把UAT设置低
我还在composer.json中添加了以下代码行：

"pre-update-cmd": [
        "@php artisan clear-compiled"
    ],

    "post-install-cmd": [
        "Illuminate\\Foundation\\ComposerScripts::postInstall",
        "php artisan optimize"
    ],
    "post-update-cmd": [
        "Illuminate\\Foundation\\ComposerScripts::postUpdate",
        "php artisan optimize"
    ]
