vue3项目开源项目运行报错::v-deep usage as a combinator has been deprecated. Use :deep(<inner-selector>) instead.

今天找了一个vue3.0开源项目，在运行的时候npm i报错

使用了npm i --legacy-peer-deps

根据以上安装依赖成功

在运行的时候有报错::v-deep usage as a combinator has been deprecated. Use :deep(<inner-selector>) instead.

原因是：的vue3.0 单文件规范::v-deep写法已经被废弃了

需要将v-deep替换成    :deep('.类名){  css  }即可
