MAPBENDER 安装失败

Question

我已经尝试安装 Mapbender 好几天了，但最后还是收到了这条消息或另一条消息

http://localhost/mapbender/app_dev.php/manager/applications

Not Found
The requested URL was not found on this server.

Apache/2.4.41 (Ubuntu) Server at localhost Port 80

或

<?php

use Symfony\Component\HttpFoundation\Request;
$loader = require_once(__DIR__ . '/../app/autoload.php');
    
require_once __DIR__.'/../app/AppKernel.php';
    
$kernel = new AppKernel('prod', false);
$request = Request::createFromGlobals();
$response = $kernel->handle($request);
$response->send();
$kernel->terminate($request, $response);
