前言
如果对 vue3 的语法不熟悉的，可以移步 Vue3.0 基础入门，快速入门。
1. 安装依赖
yarn add sass -D
// or
npm install sass -D
2. 页面样式初始化 reset.scss
/* 新建 src/assets/style/reset.scss */
/* 页面样式初始化 */

}// table {
// border-collapse: collapse;
// border-spacing: 0;
// }html,
body {width: 100%;height: 100%;font-family: "Helvetica";
}/* 新建 src/assets/style/index.scss */
/* 共用scss的集合 */
@import "./reset.scss";
3. vite.config.js 中 @ 快捷键创建
// vite.config.js
import { defineConfig } from "vite";
import vue from "@vitejs/plugin-vue";import { resolve } from "path";// https://vitejs.dev/config/
export default defineConfig({plugins: [vue()],resolve: {alias: {"@": resolve(__dirname, "./src"),},},
});4. 在 main.js 中引入 src/assets/style/index.scss
// main.js
import { createApp } from "vue";
import App from "./App.vue";import "@/assets/style/index.scss";createApp(App).mount("#app");5. 在组件中使用 scss
<!-- App.vue -->
<script setup></script><template><div class="demo"><div>yqcoder</div></div>
</template><style scoped lang="scss">
.demo {display: flex;align-items: center;justify-content: center;div {margin: 20px auto;width: 100px;height: 100px;border: 1px solid;}
}
</style>
综上
scss安装完成。下一章：Vue3+Vite+Pinia+Naive后台管理系统搭建之三：vue-router 的安装和使用
