Проблема с компиляцией ReactJs: ошибка в App.js Неожиданный токен

Question

Я следовал следующей командной строке.

npx create-react-app github-first-app

npm install --save react-tabs

npm i styled-components

npm install git-state --save

со следующими файлами кода

App.js

import React from "react";
import Layout from "./components/layout";
import NoSearch from "./components/no-search";
import Profile from "./components/profile";
import Repositories from "./components/repositories";
import useGithub from "./hooks/github-hooks";

const App = () => {
  const { githubState } = useGithub();
  return (
    <Layout>
      {githubState.hasUser ? (
        <>
          {githubState.loading ? (
            <p>Loading</p>
          ) : (
            <>
              <Profile />
              <Repositories />
            </>
          )}
        </>
      ) : (
        <NoSearch />
      )}
    </Layout>
  );
};

export default App;

и Index.html

      manifest.json provides metadata used when your web app is installed on a
      user's mobile device or desktop. See https://developers.google.com/web/fundamentals/web-app-manifest/

    <link rel="manifest" href="%PUBLIC_URL%/manifest.json" />
    <!--
      Notice the use of %PUBLIC_URL% in the tags above.
      It will be replaced with the URL of the `public` folder during the build.
      Only files inside the `public` folder can be referenced from the HTML.

      Unlike "/favicon.ico" or "favicon.ico", "%PUBLIC_URL%/favicon.ico" will
      work correctly both with client-side routing and a non-root public URL.
      Learn how to configure a non-root public URL by running `npm run build`.

но

npm start

полный сбой с сообщением, которое совсем не помогает новичку.

Ошибка компиляции.

./src/App.js Ошибка синтаксиса: C:/Workspace/bootcamps/022_CriandoUmFrontEndTotalmenteComponentizadoNaPraticaComReactJS/github- first-app/src/App.js: неожиданный токен (13:9)

Не могли бы вы сказать мне, где я ошибаюсь?
