Vue3使用ElementUI按需自动引入

1. vue create 项目名
2. 选择vue3的项目

// vue.config.js
const AutoImport = require('unplugin-auto-import/webpack')
const Components = require('unplugin-vue-components/webpack')
const { ElementPlusResolver } = require('unplugin-vue-components/resolvers')
module.exports = {
  outputDir: './build',
  // 和webpapck属性完全一致，最后会进行合并
  configureWebpack: {
    resolve: {
      alias: {
        components: '@/components'
      }
    },
    //配置webpack自动按需引入element-plus，
      plugins: [
        AutoImport({
          resolvers: [ElementPlusResolver()]
        }),
        Components({
          resolvers: [ElementPlusResolver()]
        })
      ]
  }
}

完。
