  Problem 1
    - Installation request for league/flysystem 1.1.3 -> satisfiable by league/flysystem[1.1.3].

    - league/mime-type-detection 1.4.0 requires ext-fileinfo * -> the requested PHP extension fileinfo is missing from your system.
  Problem 3

    - Installation request for laravel/framework v7.26.1 -> satisfiable by laravel/framework[v7.26.1].

  To enable extensions, verify that they are enabled in your .ini files:
    - C:\xampp\php\php.ini
  You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.

【解决方案1】：

您已从 php.ini 禁用 fileinfo 扩展。要启用扩展，请验证在 .ini 文件中已启用（在 C:\xampp\php\php.ini 中查找/添加行“extension=fileinfo”）。您也可以在终端内运行php --ini，以查看 PHP 在 CLI 模式下使用了哪些文件。

【解决方案2】：

首先，停止 XAMPP/Wamp，然后请从您的 xampp\php\php.ini 中删除起始分号 ( ; )，然后执行以下代码。

;extension=fileinfo

到

extension=fileinfo
