安装loader
cnpm i sass-loader sass-resources-loader --save-dev
修改根目录下/build/utils.js
var path = require('path')var config = require('../config')var extracttextplugin = require('extract-text-webpack-plugin')exports.assetspath = function (_path) { var assetssubdirectory = process.env.node_env === 'production' ? config.build.assetssubdirectory : config.dev.assetssubdirectory return path.posix.join(assetssubdirectory, _path)}exports.cssloaders = function (options) { options = options || {} var cssloader = { loader: 'css-loader', options: { minimize: process.env.node_env === 'production', sourcemap: options.sourcemap } } var postcssloader = { loader: 'postcss-loader', options: { sourcemap: true } } var px2rpxloader = { loader: 'px2rpx-loader', options: { basedpr: 1, rpxunit: 0.5 } } //添加该项 var sassresourceloader = { loader: 'sass-resources-loader', options: { resources: [ //修改相应路径 path.resolve(__dirname, '../src/styles/index.scss'), ] } } //添加该项 // generate loader string to be used with extract text plugin function generateloaders (loader, loaderoptions, anotherloader) { var loaders = [cssloader, px2rpxloader, postcssloader] if (loader) { loaders.push({ loader: loader + '-loader', options: object.assign({}, loaderoptions, { sourcemap: options.sourcemap }) }) } if(!!anotherloader) loaders.push(anotherloader); // extract css when that option is specified // (which is the case during production build) if (options.extract) { return extracttextplugin.extract({ use: loaders, fallback: 'vue-style-loader' }) } else { return ['vue-style-loader'].concat(loaders) } } // https://vue-loader.vuejs.org/en/configurations/extract-css.html return { css: generateloaders(), wxss: generateloaders(), postcss: generateloaders(), less: generateloaders('less'), //修改 sass: generateloaders('sass', { indentedsyntax: true },sassresourceloader), scss: generateloaders('sass',{},sassresourceloader), //修改 stylus: generateloaders('stylus'), styl: generateloaders('stylus') }}// generate loaders for standalone style files (outside of .vue)exports.styleloaders = function (options) { var output = [] var loaders = exports.cssloaders(options) for (var extension in loaders) { var loader = loaders[extension] output.push({ test: new regexp('\\.' + extension + '$'), use: loader }) } return output}
以上就是mpvue中sass全局变量的配置方法（代码）的详细内容。
