vue 运行报错 createApp.use is not a function

我的 main.js 代码如下:

import { createApp } from 'vue'
import App from './App.vue'

import VueLazyload from 'vue-lazyload' // 引入这个懒加载插件

// 或者添加 VueLazyload 选项
createApp.use(VueLazyload, {
  preLoad: 1.3,
  error: 'dist/error.png',
  loading: 'dist/loading.gif',
  attempt: 1
})

createApp(App).mount('#app')

但是在运行的时候报错,如图:

请问是为什么呢?求教!

我的版本如下:
@vue/cli 4.4.6
webpack-cli 4.2.0
webpack 4.44.1
