yarn -安装 sass

yarn add sass -dev

{"name": "vite-demo","version": "0.0.0","scripts": {"dev": "vite","build": "vite build"},"dependencies": {"sass": "^1.34.1",           //1"sass-loader": "^12.1.0",     //1"axios": "^0.21.1","vue": "^3.0.4","vue-router": "^4.0.8","vuex": "4.0"},"devDependencies": {"@vue/compiler-sfc": "^3.0.4","element-plus": "^1.0.2-beta.48","typescript": "^4.3.2","vite": "^1.0.0-rc.13"}
}

但是运行时报以下错误

问题

Could not load readline (imported by node_modules/sass/sass.dart.js): ENOENT: no such file or directory, open 'readline’

解决方案

将 1 移到 devDependencies 中去

{"name": "vite-demo","version": "0.0.0","scripts": {"dev": "vite","build": "vite build"},"dependencies": {"axios": "^0.21.1","vue": "^3.0.4","vue-router": "^4.0.8","vuex": "4.0"},"devDependencies": {"@vue/compiler-sfc": "^3.0.4","element-plus": "^1.0.2-beta.48","typescript": "^4.3.2","sass": "^1.34.1","sass-loader": "^12.1.0","vite": "^1.0.0-rc.13"}
}
