Implement ModuleManagerInterface - zend-framework2

Question

started with a new ZF2 project an get following error
Argument 1 passed to ZendDeveloperTools\Module::init() must implement interface Zend\ModuleManager\ModuleManagerInterface, null given, called in /vendor/zendframework/zend-modulemanager/src/Listener/InitTrigger.php on line 33 and defined in /vendor/zendframework/zend-developer-tools/src/ZendDeveloperTools/Module.php on line 34
It doesn't matter which Module is first in application.config.php I always got this error.

Answer 1

This is mine Module.php file. The error is saying that you need to pass a ModuleManagerInterface as first parameter in your init method. That init method has an interface. Have a look at the Zend\ModuleManager\Feature\*Interface.php files and you will see your mistake.
namespace Application;
use Zend\Mvc\MvcEvent;
use Zend\EventManager\EventInterface;
use Zend\ModuleManager\Feature\AutoloaderProviderInterface;
use Zend\ModuleManager\Feature\ConfigProviderInterface;
use Zend\ModuleManager\Feature\BootstrapListenerInterface;
use Zend\ModuleManager\Feature\InitProviderInterface;
use Zend\ModuleManager\ModuleManagerInterface;
class Module implements AutoloaderProviderInterface, ConfigProviderInterface, BootstrapListenerInterface, InitProviderInterface
{
/**
* Setup module layout
*
* #param $moduleManager ModuleManager
*/
public function init(ModuleManagerInterface $moduleManager)
{
$moduleManager->getEventManager()->getSharedManager()->attach(__NAMESPACE__, MvcEvent::EVENT_DISPATCH, function (MvcEvent $e) {
$e->getTarget()->layout('layout/layout');
});
}
/**
* Listen to the bootstrap event
*
* #param EventInterface $e
*/
public function onBootstrap(EventInterface $e)
{
}
/**
* #return array|\Traversable
*/
public function getConfig()
{
return include __DIR__.'/config/module.config.php';
}
/**
* Return an array for passing to Zend\Loader\AutoloaderFactory.
*
* #return array
*/
public function getAutoloaderConfig()
{
return [
'Zend\Loader\ClassMapAutoloader' => [
__DIR__.'/autoload_classmap.php',
],
'Zend\Loader\StandardAutoloader' => [
'namespaces' => [
__NAMESPACE__ => __DIR__.'/src/'.__NAMESPACE__,
],
],
];
}
}
