This configuration works on my local install, but not on remote site.

ExampleManager.php

<?php
namespace Application\Service;

use Application\Entity\SomeTable;

class ExampleManager 
{

    /**
     * Entity manager.
     * @var Doctrine\ORM\EntityManager
     */
    private $entityManager;

    public function __construct($entityManager) 
    {
      $this->entityManager = $entityManager;
    }

ExampleManagerFactory.php

<?php

namespace Application\Service\Factory;

use Interop\Container\ContainerInterface;
use Zend\ServiceManager\Factory\FactoryInterface;
use Application\Service\ExampleManager;

{
    public function __invoke(ContainerInterface $container, 
    $requestedName, array $options = null)
    {
        $entityManager = $container->get('doctrine.entitymanager.orm_default');

        // instantiate the service and inject dependencies
        return new ExampleManager($entityManager);
    }
}

IndexControllerFactory.php

<?php

namespace Application\Controller\Factory;

use Interop\Container\ContainerInterface;
use Zend\ServiceManager\Factory\FactoryInterface;
use Application\Controller\IndexController;

class IndexControllerFactory implements FactoryInterface
{
    public function __invoke(ContainerInterface $container, $requestedName, array $options = null)
    {
        $exampleManager = $container->get(\Application\Service\ExampleManager::class);

        // instantiate the controller and inject dependencies
        return new IndexController($exampleManager);
    }
}

Argument 1 passed to Application\Controller\IndexController::__construct() must be an instance of Application\Service\ExampleManager, none given

Seems strange for it to work locally, but not from a remote site. Is it not finding the path to my service for some reason?

回答1:

SOLVED

Wow, ok so this happened because when I had initially installed zend-skeleton awhile back I had disabled development mode, but cache files of the existing config had been created in data/cache. I discovered this while trying to think what could be different between my local and remote install. The fix is to remove the cache files.

A better explanation and credit for the solution is here: https://stackoverflow.com/a/45146213/5133172

Files are back to read only, dev mode is disabled and all works perfectly. :)
