当我在laravel中为任何项目运行composer update时，我都遇到了一个问题。它给予了我这个错误：无法将您的要求解析为一组可安装的程序包。
Problem 1
- Root composer.json requires php ^7.1.3 but your php version (8.1.0) does not satisfy that requirement.
Problem 2
- laravel/framework[v5.7.0, ..., 5.7.x-dev] require php ^7.1.3 -> your php version (8.1.0) does not satisfy that requirement.
- Root composer.json requires laravel/framework 5.7.* -> satisfiable by laravel/framework[v5.7.0, ..., 5.7.x-dev].我尝试从composer.json更改它，但仍然不起作用，我还尝试了composer install --ignore-platform-reqs给我其他错误：

您的php版本太高（8.1）。Laravel 5.x与php 8不兼容。
您有两个选择：
1.升级你的laravel安装（至少在8.x版本之前遵循指南）
1.降级你的php版本

你已经升级了你的机器上的php版本。所以，为了让你的laravel应用程序知道我已经升级到了新版本的php，请执行以下操作：
在你的
root目录中打开composer.json文件，在require对象中有提到的php版本。将其更改为如下。如果这不起作用，那么只使用您机器上安装的当前php版本。

解决了！！我使用全局 composer 与XAMPP服务器的PHP。

在我的情况下：我的laravel 8.9
我尝试使用^8.8
然后运行composer u
一切OK
