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，ng add @clr/angular但我不断收到与不兼容性相关的错误（报告）：

我尝试指定清晰度版本 (@clr/angular@12) 并使用该命令--force，但它们都导致了相同的错误。网上似乎有很多关于 npm cache 的帖子，但他们对什么是合适的解决方案的看法各不相同，这让我害怕仅仅尝试就会让事情变得更糟。

你能帮忙吗？

uj5u.com热心网友回复：

您的应用程序（或 angular 的）的某些依赖项未完全升级以与 npm 8.x 一起使用（更具体地说是与新版本的 package.json 结构）

尝试

npm  i @clr/angular --legacy-peer-deps

降级到 npm 7.x 也应该有效。
