VUE-cli3使用 svg-sprite-loader

npm install svg-sprite-loader --save-dev

const path = require('path')
function resolve(dir) {

}
module.exports = {
 chainWebpack: config => {
  config.module.rules.delete("svg"); //重点:删除默认配置中处理svg,
  //const svgRule = config.module.rule('svg')
  //svgRule.uses.clear()
  config.module
   .rule('svg-sprite-loader')
   .test(/\.svg$/)
   .include
   .add(resolve('src/icons')) //处理svg目录
   .end()
   .use('svg-sprite-loader')
   .loader('svg-sprite-loader')
   .options({
    symbolId: 'icon-[name]'
   })
 },
 configureWebpack: () => ({
  // resolve: {
  //  alias: require('./alias.config').webpack
  // }
  // module: {
