vite.config.ts

// https://vite.dev/config/
export default defineConfig({plugins: [vue(),],resolve: {alias: {'@': fileURLToPath(new URL('./src', import.meta.url)) //相对路径别名配置，@代替src，用于打包时路径转换},},css: {preprocessorOptions: {// 引入公共scss变量scss: {// 引入 varibles.scss 这样就可以在全局中使用 varibles.scss中预定义的变量了// 给导入的路径最后加上 ;// as 后面是定义的环境变量//   如果写as * ，可以直接使用变量名，如：变量名//   如果不写as *, 默认文件名即：variables, 使用variables.变量名//   如果是as vars，则使用vars.变量名additionalData: '@use "@/assets/styles/variables" as *;',},},},
