我正在尝试导入组件，但无法执行
我还尝试过导出默认类App extends React.Component而不是类App extends Component（），但它没有解决我的问题

import React from 'react';
import React,{Component} from 'react';
import './App.css';

class App extends Component() {
  constructor(props){

  }
  render() {
  return (
    <div className="App">
      <table className="titleBar">
        <tbody>
          <tr>
            <td>
              <img alt="app icon" width="50" src="primary_green.svg"/>
            </td>
            <td width="8"/>
            <td>
              <h1>MovieDb Search</h1>
            </td>
          </tr>
        </tbody>
      </table>
      <input style={{
        fontSize: 24,
        display: 'block',
        width: '99%',
        paddingTop: 8,
        paddingBottom: 8,
        paddingLeft: 16
      }} placeholder="Enter Search Term"/>
    </div>
  );
 }
}

export default App;

Line 2:  Parsing error: Identifier 'React' has already been declared

import React from 'react';
import React,{Component} from 'react';
import './App.css';
