vue3在vue.config.js里配置路径别名

const { defineConfig } = require('@vue/cli-service')
const path = require("path");
const resolve = (dir) => path.join(__dirname, dir);

module.exports = defineConfig({
  chainWebpack: config => {
    config.resolve.alias
      .set('@', resolve('src'))
      .set('assets', resolve('src/assets'))
      .set('styles', resolve('src/assets/styles'))
      .set('components', resolve('src/components'))
  }
})
