Question

尝试运行我的React应用时收到以下错误：

D：/React/my-components/src/App.tsx D：/React/my-components/src/App.tsx（23,4）中的TypeScript错误： JSX元素类型'Confirm'不是JSX元素的构造函数。类型'Confirm'缺少类型'ElementClass'中的以下属性：context，setState，forceUpdate，props和另外2个。 TS2605

21 |         </a>
22 |       </header>
23 |      <Confirm />
   |      ^
24 |     </div>
25 |   );
26 | }

这是我的确认组件代码

import * as React from "react";

class Confirm extends React.Component{
	 render(){
					return (
						<div className="confirm-wrapper confirm-visible">
			<div className="confirm-container">
			<div className="confirm-title-container">
			<span>This is where our title should go</span>
			</div>
			<div className="confirm-content-container">
			<p>This is where our content should go</p>
			</div>
			<div className="confirm-buttons-container">
			<button className="confirm-cancel">Cancel</button>
			<button className="confirm-ok">Okay</button>
			</div>
			</div>
			</div>
					);
	}
	
}
export default Confirm;

和App.tsx代码

import React from 'react';
import logo from './logo.svg';
import './App.css';
import Confirm from './Confirm';

const App: React.FC = () => {
  return (
    <div className="App">
      <header className="App-header">
        <img src={logo} className="App-logo" alt="logo" />
        <p>
          Edit <code>src/App.tsx</code> and save to reload.
        </p>
        <a
          className="App-link"
          href="https://reactjs.org"
          target="_blank"
          rel="noopener noreferrer"
        >
          Learn React
        </a>
      </header>
	  <Confirm />
    </div>
  );
}

export default App;

这是我的package.json

{
  "name": "my-components",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "@types/jest": "24.0.18",

Answer 1

谢谢，我通过运行以下命令解决了该错误

纱线升级@ types / react @ latest

Answer 2

我有一个名为 Component.tsx（驼峰式）的组件和一个名为 component.ts（小写）的帮助程序，这似乎使它们变得混乱。我也在同一个文件中导入它们，所以我只是重命名了组件一。

类型“ xxx”缺少类型“ ElementClass”中的以下属性：context，setState，forceUpdate，props和另外2个。 TS2605
