【问题描述】：
运行composer install 命令时出现异常错误。
它需要 PHP 7.3 而我有 PHP 8.0.0。这个问题与 Override PHP base dependency in composer 不同，因为我的 PHP (8.0.0) 版本比它要求的要高。为什么它不起作用？

stackoverflow.com/questions/32838881/… 我的问题与此不同，因为我的版本比要求的高。

是的，但您也可以模拟那里的答案中提到的平台。
-
^7.3 表示版本 7.3.0 或更高版本。但是，它与版本 8 或更高版本不兼容
-
视情况而定。你通过码头工作吗？这意味着您的容器具有所需的 php 版本。如果您在更新之外尝试并且您的操作系统的 php 版本更高，那么您将收到此警告。解决此问题的一种方法是使用 --ignore-platform-reqs 标志运行 composer update。
-
'composer install --ignore-platform-reqs' 你也可以使用。它可能适用于你的情况。
