编译失败./src/App.js未找到模块：无法解析

Question

当我开始运行本地服务器时出现以下错误：

无法编译./src/App.js未找到模块：无法解析'/ home / sol / React / kuehnfotografie / src'中的'./Main'

import React, { Component } from 'react';
import ReactDOM from 'react-dom';
import Main from './Main';
import { Provider, createComponent } from 'react-fela';
import { createRenderer } from 'fela';

class App extends React.Component {
  render() {
    return (
      <div className="content">
        <Main />
      </div>
    );
  }
}

export default App;

Folder structure

这是main.js文件：

import React from 'react';
import ReactDOM from 'react-dom';
import { Provider, createComponent } from 'react-fela';
import { createRenderer } from 'fela';
import Header from './main/Header';
import Content from  './main/Content';
import Footer from './main/Footer';

class Main extends React.Component {
  render() {
    return (
      <div className="main">
        <Header />
        <Content />
        <Footer />
      </div>
    );
  }
} 

export default Main;
