plus composer 安装扩展时报错，需要 dcat/laravel-admin 2.0 。plus如何安装这些扩展？项目中时常会用到登录验证码、列表视频预览、图片裁剪上传等扩展。
以下是报错信息

You can also try re-running composer require with an explicit version constraint
, e.g. "composer require guanguans/dcat-login-captcha:*" to figure out if any ve
rsion is installable, or "composer require guanguans/dcat-login-captcha:2.1" if
you know which you need.
Installation failed, reverting ./composer.json and ./composer.lock to their orig
inal content.
