webman下执行 composer run-script post-package-install

问题描述

composer是2.1.6的

[root@635ed185d2dc webman]# composer run-script post-package-install
> support\Plugin::install

Fatal error: Uncaught Error: Call to undefined method Composer\Script\Event::getOperation() in /data/www/webman/webman/vendor/workerman/webman-framework/src/support/Plugin.php:14

这个不能单独执行吗？
