我正在按照一个书籍项目练习 Angular，该项目需要通过 cmd 为该项目安装 Clarity 库

我尝试指定清晰度版本（@clr/angular@12）并使用命令
--force请帮忙吗？
您的应用程序（或 Angular 的）的一些依赖项尚未完全升级以与 npm 8.x 一起使用（更具体地说，是使用新版本的 package.json 结构）
尝试
npm i @clr/angular --legacy-peer-deps
降级到 npm 7.x 也应该可以。
我遇到了同样的问题，尝试运行 npm install @clr/ui @clr/angular @cds/core --force 并且我能够安装清晰度。
