問(wèn)題所在：

index.js

import React from 'react';
import ReactDOM from 'react-dom/client';
import './index.scss';
import App from './App';
import reportWebVitals from './reportWebVitals';

const root = ReactDOM.createRoot(document.getElementById('root'));
 root.render(
    <React.StrictMode>
         <App/>
     </React.StrictMode>
);
reportWebVitals();

改成

import React from 'react';
import ReactDOM from 'react-dom/client';
import './index.scss';
import App from './App';
import reportWebVitals from './reportWebVitals';

const root = ReactDOM.createRoot(document.getElementById('root'));
root.render(<App/>);
reportWebVitals();
