你的state写错地方了，

class AppContainer extends React.Component {
    constructor() {
        super()
        this.state = {
            name: '案例'
        }
    }
    
    ...
    
    render() {
        ...
    }
}

这么写吧。

写成这样报错么？

import React from 'react'
const App = ({ name }) => {
  return <div>{name}</div>
}
export default App

另外具体是报的什么错误啊
