本篇文章给大家带来的内容是关于mpvue中sass全局变量的配置方法（代码），有一定的参考价值，有需要的朋友可以参考一下，希望对你有所帮助。

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({},{

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',{},//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

}
