模块未找到:无法解析'./components/player‘中的’./成绩板-app/src/components‘

Question

我使用创建-反应-应用程序来构建一个小的反应应用程序。完整的代码存储在github中

我的档案结构：

src
  components
    Players.js
    Player.js
App.css
App.js
index.css
index.js
...

App.js：

import React from 'react';
import './App.css';
import PropTypes from 'prop-types';// used to fix the error: 'PropTypes' is not defined
import Header from './components/Header';
import Players from './components/Players';

const App = (props) => (
  <div className="scoreboard">
    <Header title={props.title} />
    <Players />
  </div>
  );

App.propTypes = {
  title: PropTypes.string.isRequired
};


export default App;

Player.js：

import React from 'react';

const Player = (props) => (
  <div className="player">
    <div className="player-name">
      Jim Hoskins
    </div>
    <div className="player-score">
      <div className="counter">
        <button className="counter-action decrement"> - </button>
        <div className="counter-score">31</div>
        <button className="counter-action increment"> + </button>
      </div>
    </div>
  </div>
);

export default Player;

Players.js：

import React from 'react';
import Player from './components/Player';

const Players = () => (
  <div className="players">
    <div className="player">
      <div className="player-name">
        Jim Hoskins
      </div>
      <div className="player-score">
        <div className="counter">
          <button className="counter-action decrement"> - </button>
          <div className="counter-score">31</div>
          <button className="counter-action increment"> + </button>
        </div>
      </div>
    </div>
    <div className="player">
      <div className="player-name">
        Juan Li
      </div>
      <div className="player-score">
        <div className="counter">
          <button className="counter-action decrement"> - </button>
          <div className="counter-score">30</div>
          <button className="counter-action increment"> + </button>
        </div>
      </div>
    </div>
  </div>
)

export default Players;

import Player from './components/Player';行将导致以下错误：

但是，如果我将这一行放在App.js文件的顶部，它就不会报告这样的编译错误。我真的想知道我的代码到底有什么问题？

Answer 1

您的文件路径错误。Player与Players位于同一个文件夹中，所以您只需说import Player from './Player'

Answer 2

• 删除node_modules目录
• 删除包-lock.json文件
• 运行npm安装
• 运行npm启动
