我正在尝试使用League / route PHP软件包来管理友好的路线：

https://route.thephpleague.com/4.x/usage/

到目前为止，我所做的就是将它们的“ Hello world”示例复制到我的index.php文件中：

<?php declare(strict_types=1);

require './vendor/autoload.php';

use Psr\Http\Message\ResponseInterface;
use Psr\Http\Message\ServerRequestInterface;

$request = Zend\Diactoros\Serverrequestfactory::fromGlobals(
    $_SERVER,$_GET,$_POST,$_COOKIE,$_FILES
);

$router = new League\Route\Router;

// map a route
$router->map('GET','/asdf',function (ServerRequestInterface $request) : ResponseInterface {
    $response = new Zend\Diactoros\Response;
    $response->getBody()->write('<h1>Hello,World!</h1>');
    return $response;
});

$response = $router->dispatch($request);

// send the response to the browser
(new Zend\HttpHandlerRunner\Emitter\SapiEmitter)->emit($response);

然后出现以下错误：
