错误“ Root poser.json 需要 php ^ 7.3，但是您的 php 版本(8.0.0)不满足该要求”

在运行 composer install命令时出现了一个不寻常的错误。

它需要 PHP 7.3，而我有 PHP 8.0.0。这个问题与 Href = “ https://stackoverflow. com/questions/32838881/Override-PHP-base-ency- in-writer”> Override PHP base endyance in writer 在作曲家中覆盖 PHP 基本依赖性不同，因为我的 PHP 版本(8.0.0)比它需要的更高。为什么不起作用？
