带有React的ESLint会给出“ no-unused-vars”错误

我已经设定eslint＆eslint-plugin-react。

当我运行ESLint时，linter会no-unused-vars为每个React组件返回错误。

我假设它没有意识到我正在使用JSX或React语法。有任何想法吗？

例：

app.js

import React, { Component } from 'react';
import Header from './header.js';

export default class App extends Component {
  render() {
    return (
      <div>
        <Header />
        {this.props.children}
      </div>
    );
  }
}

短绒错误：

/my_project/src/components/app.js
  1:8  error  'React' is defined but never used   no-unused-vars
  2:8  error  'Header' is defined but never used  no-unused-vars

这是我的.eslintrc.json文件：
