错误“根composer.json需要php ^7.3，但您的php版本（8.0.0）不满足该要求”[重复]

Question

我在运行

composer install

命令时遇到异常错误。

它需要 PHP 7.3，而我有 PHP 8.0.0。这个问题与 Override PHP base dependency incomposer 不同，因为我的 PHP 版本（8.0.0）比所需的版本更高。为什么不起作用？

从评论中发现以下命令在一定程度上可以工作。它也适用于我的情况

composer install --ignore-platform-reqs

Answer 1

这是因为在您的项目中 composer.json 文件中您有：

"require": {
    "php": ">=7.3",
    .....
},

尝试将此要求更新为：

"require": {
    "php": "^7.3||^8.0",
    .....
},
