I am currently working through the Zend 3 tutorial. The only difference is I am using an Examples table/class instead of Albums. Everything appears to be as per spec except I am getting the following error every time I try to access the dev server:
Fatal error: Uncaught exception 'Zend\ServiceManager\Exception\ServiceNotFoundException' with message 'A plugin by the name "Example\Segment" was not found in the plugin manager Zend\Router\RoutePluginManager' in C:\Websites\ZEND2\vendor\zendframework\zend-servicemanager\src\AbstractPluginManager.php:133 Stack trace: #0 C:\Websites\ZEND2\vendor\zendframework\zend-router\src\SimpleRouteStack.php(280): Zend\ServiceManager\AbstractPluginManager->get('Example\Segment', Array) #1 C:\Websites\ZEND2\vendor\zendframework\zend-router\src\Http\TreeRouteStack.php(201): Zend\Router\SimpleRouteStack->routeFromArray(Array) #2 C:\Websites\ZEND2\vendor\zendframework\zend-router\src\Http\TreeRouteStack.php(151): Zend\Router\Http\TreeRouteStack->routeFromArray(Array) #3 C:\Websites\ZEND2\vendor\zendframework\zend-router\src\SimpleRouteStack.php(142): Zend\Router\Http\TreeRouteStack->addRoute('example', Array) #4 C:\Websites\ZEND2\vendor\zendframework\zend-router\src\SimpleRouteStack.php(86): Zend\Router\SimpleRouteStack->addRoutes(Array) in C:\Websites\ZEND2\vendor\zendframework\zend-servicemanager\src\AbstractPluginManager.php on line 133
