Module.php

<?PHP

   

    namespace moduleNema;

       use moduleNema\twigExtensions\NemaTwigExtension as NemaTwigExtension;

       use Craft;
 

    use craft\services\Elements;


 

    use yii\base\Event;


 class Module extends \yii\base\Module
  {
      public function init()
      {
          parent::init();

          Event::on(Elements::class, Elements::EVENT_AFTER_SAVE_ELEMENT, function( Event 
           $event ) {
        
           });
        
            if ( Craft::$app->request->getIsSiteRequest() ) {
               // Add in our Twig extension
               $extension = new NemaTwigExtension();
               Craft::$app->view->registerTwigExtension($extension);
            }        
         }
      }

on composer:

"autoload": {
        "psr-4": {
          "modules\\": "modules/",
          "moduleNema\\": "modules/moduleNema"
        },
      },

I try all kinds of stuff, and still can solve my error

I rename all folders like this:

modules

      -> ModulesNema
         -> Controllers

         -> Services
            -> Dark.php
            -> Rent.php

         -> TwigExtensions
            -> NemaTwigExtensions.php

         -> Module.php

      -> Module.php

Then change all namespace like

use Modules\ModuleNema\TwigExtensions\NemaTwigExtensions;
use Modules\ModuleNema\Services\Dark;
use Modules\ModuleNema\Services\Rent;

on composer:

"autoload": {
        "psr-4": {
          "Modules\\": "modules/",
          "ModuleNema\\": "modules/ModuleNema"
        },
      },

and run

composer dump-autoload -o

now all it's working with composer 2
