+
+[node-sass 替换为 sass](https://blog.csdn.net/weixin_41223575/article/details/128687533)
+
+node-sass 替换为 sass
+原因：安装 node-sass 的项目依赖 node 的版本，维护的项目依赖的 node 版本和自己电脑安装的 node 版本不一致的问题（没必要一直升级 node 版本，把时间花在搞环境上）。
+
+方案：
+```
+1.要么电脑安装 nvm 管理切换不同的 node 版本，切换还是不太方便，而且不能同时启动依赖 node 版本不一样的两个项目。
+
+2.项目的依赖不应该再依赖 node 的版本，比如 node-sass 这种只用于开发环境的依赖项，所以把 node-sass 替换为 sass（推荐）。
+
+步骤：卸载 node-sass ，安装 sass，项目全局搜索 ::v-deep , 把 ::v-deep 替换为 ::v-deep。
+
+1.卸载 node-sass：npm uninstall node-sass
+
+2.安装 sass：npm install sass --save-dev
+
+3.全局搜索替换：::v-deep 替换为 ::v-deep
