    - league/flysystem 1.1.10 requires ext-fileinfo * -> it is missing from your system. Install or enable PHP's fileinfo extension.

To enable extensions, verify that they are enabled in your .ini files:
    - D:\myphp\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.

解决方案：

修改安装的 php 目录下，php.ini 解开 extension=fileinfo 的注释，去点前面的分号即可

 修改完后，在执行 composer install 命令，可能有两种情况如下：

1. 执行成功，可以进行下一步
2. 还出现错误，错误代码如下：
