      // 重定向
      {
        path: '/',
        element: <Navigate to="home" replace />
      },
      {
        path: '/home',
        Component: home
      }
    ]
  }

    <div>
      <h1>Welcome to my React App!</h1>
      <p>This is the main component.</p>
      {/* 显示子文件位置 */}

      <p>Welcome to the Home Page!</p>
    </div>
  );
}
export default home
