npm install react-router-dom --save

import {BrowserRouter,Route,Link} from 'react-router-dom';
import Counter from './Counter';
import ButtonSize from './myBtn';
/* 是jsx语法，需要React的支持 */
ReactDOM.render(

document.getElementById('root')
);
// If you want your app to work offline and load faster, you can change

// Learn more about service workers: https://bit.ly/CRA-PWA
serviceWorker.unregister();

import { Button, Radio } from 'antd';
import { DownloadOutlined } from '@ant-design/icons';
import {Link} from 'react-router-dom';
class ButtonSize extends React.Component {
state = {
size: 'large',
};
handleSizeChange = e => {
this.setState({ size: e.target.value });
};
render() {
const { size } = this.state;
return (
