I've made all Zend Framework 2 tutorials stopping in "routing", exactly this: https://docs.zendframework.com/tutorials/in-depth-guide/understanding-routing/
My problem is I've made everything in my code as suggested but I'm facing this error when I try the route in my local http://localhost:8080/blog, accessible after running php -S 0.0.0.0:8080 -t public public/index.php:
Fatal error: Uncaught exception 'Zend\ServiceManager\Exception\ServiceNotFoundException' with message 'A plugin by the name "Blog\Segment" was not found in the plugin manager Zend\Router\RoutePluginManager' in C:_PROJETOS\Knowledge\ZendFramework2\5-InDepth\vendor\zendframework\zend-servicemanager\src\AbstractPluginManager.php:131 Stack trace: #0 C:_PROJETOS\Knowledge\ZendFramework2\5-InDepth\vendor\zendframework\zend-router\src\SimpleRouteStack.php(280): Zend\ServiceManager\AbstractPluginManager->get('Blog\Segment', Array) #1 C:_PROJETOS\Knowledge\ZendFramework2\5-InDepth\vendor\zendframework\zend-router\src\Http\TreeRouteStack.php(201): Zend\Router\SimpleRouteStack->routeFromArray(Array) #2 C:_PROJETOS\Knowledge\ZendFramework2\5-InDepth\vendor\zendframework\zend-router\src\Http\TreeRouteStack.php(151): Zend\Router\Http\TreeRouteStack->routeFromArray(Array) #3 C:_PROJETOS\Knowledge\ZendFramework2\5-InDepth\vendor\zendframework\zend-router\src\SimpleRouteStack.php(142): Zend\Router\Http\TreeRouteStack->addRoute('deta in C:_PROJETOS\Knowledge\ZendFramework2\5-InDepth\vendor\zendframework\zend-servicemanager\src\AbstractPluginManager.php on line 131
I can't see whats happening to solve the problem, there was a long time i don't code with Zend Framework 2 unfortunately.
I'm very grateful for any help in understanding and solving it!

Within your module.config.php - missing the following namespace:
use Zend\Router\Http\Segment;
That is why it's trying to look for Blog\Segment as you forgot to use the right namespace for the Segment::class and thus looking for the class within the current namespace.
