Composer 更新未运行

Question

当我在 laravel 中为任何项目运行 composer update 时遇到问题。它给了我这个错误： 无法将您的要求解析为一组可安装的软件包。

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].

我试图从 composer.json 更改它，但仍然无法正常工作 我还尝试composer install --ignore-platform-reqs 给了我其他错误：

那么您知道我应该如何处理该错误吗？有人可以帮忙吗？？？

Answer 1

您的 php 版本太高 (8.1)。 Laravel 5.x 与 php 8 不兼容。
您有两种选择：

1. Upgrade 你的 laravel 安装（按照指南至少到 8.x 版本）
2. 降级你的php版本

Answer 2

您已经升级了您机器中的 php 版本。因此，为了让您的 laravel 应用程序知道我已经升级到更新版本的 php，请执行以下操作，

在您的root 目录中打开composer.json 文件，在require 对象中提到了php 版本。将其更改为关注。

"php": "7.1.3|8.0",

如果这不起作用，那么只需使用您机器上安装的当前 php 版本。

"php": "8.0",

解决了！！ 我将全局作曲家与 XAMPP 服务器一起用于 php。
