php laravel框架 项目搭建环境运行 composer install 遇到问题

错误代码如下：

Installing dependencies from lock file (including require-dev)Verifying lock file contents can be installed on current platform.Your lock file does not contain a compatible set of packages. Please run composer update.  Problem 1    - league/flysystem is locked to version 1.1.10 and an update of this package was not requested.    - league/flysystem 1.1.10 requires ext-fileinfo * -> it is missing from your system. Install or enable PHP's fileinfo extension.  Problem 2    - league/mime-type-detection is locked to version 1.11.0 and an update of this package was not requested.    - league/mime-type-detection 1.11.0 requires ext-fileinfo * -> it is missing from your system. Install or enable PHP's fileinfo extension.  Problem 3    - phpoffice/phpspreadsheet is locked to version 1.26.0 and an update of this package was not requested.    - phpoffice/phpspreadsheet 1.26.0 requires ext-fileinfo * -> it is missing from your system. Install or enable PHP's fileinfo extension.  Problem 4    - league/flysystem 1.1.10 requires ext-fileinfo * -> it is missing from your system. Install or enable PHP's fileinfo extension.    - league/flysystem-aws-s3-v3 1.0.30 requires league/flysystem ^1.0.40 -> satisfiable by league/flysystem[1.1.10].    - league/flysystem-aws-s3-v3 is locked to version 1.0.30 and an update of this package was not requested.To enable extensions, verify that they are enabled in your .ini files:    - D:\myphp\php.iniYou 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：
