You are using Composer 2, which some of your plugins seem to be incompatible with. Make sure you update your plugins or report a plugin-issue to ask them to support Composer 2.

然后，如果我总是在错误下面运行composer update，

Answer 1

这是你遗漏的主要信息：

laminas/laminas-dependency-plugin 1.0.4 requires composer-plugin-api ^1.1 -> found composer-plugin-api[2.0.0] but it does not match the constraint

它会告诉您正在使用Composer v2，而您的一些包仍然需要Composer v1。您应该将Composer降级到v1，或者升级软件包。

有选择的升级可以通过类似于composer update laminas/laminas-dependency-plugin magento/composer-root-update-plugin的方式来完成
