vue-cli(webpack)创建的项目，拓展tsx时，报错如下图和代码

报错

代码

安装依赖

cnpm install -D @vue/babel-plugin-jsx

配置babel.config.js

module.exports = {
  presets: ['@vue/cli-plugin-babel/preset'],
  plugins: ['@vue/babel-plugin-jsx']
}

vue.config.js

// const path = require('path')
module.exports = {
  devServer: {
    port: 8080, // 端口号
    compress: true,
    disableHostCheck: true // webpack4.0 开启热更新
  },
  chainWebpack: config => {
    config.resolve.symlinks(true) // 修复热更新失效
  }
}

tsconfig.json

    "jsx": "preserve",
    "jsxFactory": "h",
    "jsxFragmentFactory": "Fragment",

main.ts

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

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

about.tsx

import { defineComponent, reactive, onMounted } from 'vue';

export default defineComponent({
  setup() {
    const data = reactive({ count: 0 });

    onMounted(() => {
      data.count = 5;
    });

    const clickHandler = () => data.count++

    return () => (
      <>
        <span style={{ marginRight: '10px' }}>{ data.count }</span>
        <button onClick={clickHandler}>+</button>
      </>
    )
  }
})

需要在你的 vite.config.js 加入 plugin-vue-jsx

import { defineConfig } from 'vite'
import vueJsx from '@vitejs/plugin-vue-jsx'

export default defineConfig({
  plugins: [
    // ...
    vueJsx()   
  ]
})
