javascript - 如何修复react中eslint的 "Component is defined but never used"？

Question

这是我在 .eslintrc.json 文件中的 eslint 配置:

 {
        "env": {
            "browser": true,
            "commonjs": true,
            "es6": true
        },
        "extends": "eslint:recommended",
        "parserOptions": {
            "ecmaVersion": 6,
            "ecmaFeatures": {
                "experimentalObjectRestSpread": true,
                "jsx": true
            },
            "sourceType": "module"
        },
        "plugins": [
            "react"
        ],
        "rules": {
            "react/jsx-uses-react": "error",
            "react/jsx-uses-vars": ["error"],
            "indent": 0,
            "linebreak-style": [
                "error",
                "windows"
            ],
            "quotes": [
                "error",
                "single"
            ],
            "semi": [
                "error",
                "always"
            ]
        },
        "settings": {
        "react": {
          "pragma": "React",
          "version": "15.0"
        }
      }
    }

这是下面 React 工作区中的 app.jsx:

 import React, { Component } from 'react';

    class App extends React.Component {
      render () {
        return(
          <h1>Hello Newbies</h1>
        );
      }
    }

    export default App;

我从 eslint 中收到错误'Component'已定义但从未使用过。到目前为止，除了挖掘网络之外，我无法通过任何操作来解决此问题。我该如何修复这个错误？非常感谢您的帮助。
