Php 获得；ServiceNotFoundException“；从"；“深入”；辅导的

我已经制作了所有Zend Framework 2教程，仅限于“路由”，具体如下：

我的问题是，我已经按照建议在代码中创建了所有内容，但当我在本地

http://localhost:8080/blog

，运行php-S 0.0.0.0:8080-t public/index.php后可访问

致命错误：未捕获异常“Zend\ServiceManager\exception\ServiceNotFoundException”，消息为“一个名为“Blog\Segment”的插件”在C:_PROJETOS\Knowledge\ZendFramework2\5-InDepth\vendor\zendframework\Zend servicemanager\src\AbstractPluginManager.php中的插件管理器Zend\Router\RoutePluginManager'中找不到。php:131堆栈跟踪：#0 C:_PROJETOS\Knowledge\ZendFramework2\5-InDepth\vendor\zendframework\zendframework\Zend Router\src\SimpleRouteStack.php（280）：Zend\ServiceManager\AbstractPluginManager->get（'Blog\Segment'，Array）#1c:_-PROJETOS\Knowledge\ZendFramework2\5-InDepth\vendor\zendframework\Zend-router\src\Http\TreeRouteStack.php（201）：Zend\router\SimpleRouteStack->routeFromArray（Array）#2 C:#u PROJETOS\Knowledge\ZendFramework2\5-InDepth\vendor\zendframework\zend router\src\Http\TreeRouteStack.php（151）：zend\router\Http\TreeRouteStack->routeFromArray（Array）#3 C:#u PROJETOS\Knowledge\zendframework\ZendFramework2\5-InDepth\vendor\zendframework\zendframework\zend\zend->router\src\SimpleRouteStack\SimpleRouteStack.php（'deta in C:_PROJETOS\Knowledge\ZendFramework2\5-InDepth\vendor\zendframework\zend servicemanager\src\AbstractPluginManager.php，第131行）

我看不出发生了什么来解决这个问题，很遗憾，我很久没有使用Zend Framework 2编写代码了

我非常感谢在理解和解决它方面的任何帮助

模块.config.php中的
-缺少以下命名空间：

use Zend\Router\Http\Segment;

这就是为什么它试图查找
Blog\Segment
，因为您忘记了为
Segment:：class
使用正确的名称空间，从而在当前名称空间中查找该类。

感谢@Kwido的帮助，它丢失了对Segment的引用！我尝试了，但错误仍然存在。.我更新了代码，并设置了错误通过完整消息。我查看了我的代码，它现在正在运行，感谢解决方案和解释！感谢帮助@Kwido，它缺少对段的引用！我尝试了，但错误仍然存在。我更新了我的代码，并将错误放置在完整消息中。我查看了我的代码，它现在正在运行，感谢解决方案和解释！
