前言

系统：windows系统
sass版本: 1.42.1 compiled with dart2js 2.14.2

第一步： 全局安装sass

// 使用淘宝镜像安装，确保安装成功
cnpm install -g sass
or
yarn add global  sass 

查看sass否安装成功:在控制台 输入sass --version，出现版本，表示安装成功

详情请查看官网：https://www.sass.hk/ 或者 https://www.runoob.com/sass/sass-install.html

第二步：webstorm设置scss 编译成wxss

新建一个fileWatchers,点击Apply，然后点ok

Arguments输入:

$FileName$:$FileNameWithoutExtension$.wxss --no-source-map

Output paths to refresh输入

$FileNameWithoutExtension$.wxss

第三步：验证

如需要生成map文件，Arguments输入:去掉--no-source-map

效果如下图所示：
