Hey 🙂 Ich versuche gerade Shopware über XAMPP zu installieren. Alles klappt bis ich dann zur Database configuration komme, beim installations screen kommt dann diese Fehlermeldung: ## Error Received an error message. **URL:** importDatabase **Message:** Internal Server Error Please try to fix this error and restart the update. ### Response # Slim Application Error The application could not run because of the following error: ## Details **Type:** Error **Message:** Class „Symfony\Component\HttpKernel\Exception\HttpException“ not found **File:** /opt/lampp/htdocs/shopware3/vendor/shopware/core/Framework/ShopwareHttpException.php **Line:** 8 ## Trace #0 /opt/lampp/htdocs/shopware3/vendor/shopware/recovery/Common/vendor/composer/ClassLoader.php(478): include() #1 /opt/lampp/htdocs/shopware3/vendor/shopware/recovery/Common/vendor/composer/ClassLoader.php(346): Composer\Autoload\includeFile(‚/opt/lampp/htdo…‘) #2 /opt/lampp/htdocs/shopware3/vendor/shopware/core/Framework/Migration/Exception/InvalidMigrationClassException.php(7): Composer\Autoload\ClassLoader-\>loadClass(‚Shopware\Core\F…‘) #3 /opt/lampp/htdocs/shopware3/vendor/shopware/recovery/Common/vendor/composer/ClassLoader.php(478): include(‚/opt/lampp/htdo…‘) #4 /opt/lampp/htdocs/shopware3/vendor/shopware/recovery/Common/vendor/composer/ClassLoader.php(346): Composer\Autoload\includeFile(‚/opt/lampp/htdo…‘) #5 /opt/lampp/htdocs/shopware3/vendor/shopware/core/Framework/Migration/MigrationCollection.php(190): Composer\Autoload\ClassLoader-\>loadClass(‚Shopware\Core\F…‘) #6 /opt/lampp/htdocs/shopware3/vendor/shopware/core/Framework/Migration/MigrationCollection.php(152): Shopware\Core\Framework\Migration\MigrationCollection-\>loadMigrationSteps() #7 /opt/lampp/htdocs/shopware3/vendor/shopware/core/Framework/Migration/MigrationCollection.php(100): Shopware\Core\Framework\Migration\MigrationCollection-\>ensureStepsLoaded() #8 /opt/lampp/htdocs/shopware3/vendor/shopware/core/Framework/Migration/MigrationCollection.php(58): Shopware\Core\Framework\Migration\MigrationCollection-\>getMigrationSteps() #9 /opt/lampp/htdocs/shopware3/vendor/shopware/recovery/Install/src/app.php(607): Shopware\Core\Framework\Migration\MigrationCollection-\>sync() #10 [internal function]: Closure-\>{closure}(Object(Slim\Http\Request), Object(Slim\Http\Response), Array) #11 /opt/lampp/htdocs/shopware3/vendor/shopware/recovery/Common/vendor/slim/slim/Slim/Handlers/Strategies/RequestResponse.php(40): call\_user\_func(Object(Closure), Object(Slim\Http\Request), Object(Slim\Http\Response), Array) #12 /opt/lampp/htdocs/shopware3/vendor/shopware/recovery/Common/vendor/slim/slim/Slim/Route.php(281): Slim\Handlers\Strategies\RequestResponse-\>\_\_invoke(Object(Closure), Object(Slim\Http\Request), Object(Slim\Http\Response), Array) #13 /opt/lampp/htdocs/shopware3/vendor/shopware/recovery/Common/vendor/slim/slim/Slim/MiddlewareAwareTrait.php(117): Slim\Route-\>\_\_invoke(Object(Slim\Http\Request), Object(Slim\Http\Response)) #14 /opt/lampp/htdocs/shopware3/vendor/shopware/recovery/Common/vendor/slim/slim/Slim/Route.php(268): Slim\Route-\>callMiddlewareStack(Object(Slim\Http\Request), Object(Slim\Http\Response)) #15 /opt/lampp/htdocs/shopware3/vendor/shopware/recovery/Common/vendor/slim/slim/Slim/App.php(503): Slim\Route-\>run(Object(Slim\Http\Request), Object(Slim\Http\Response)) #16 /opt/lampp/htdocs/shopware3/vendor/shopware/recovery/Install/src/app.php(168): Slim\App-\>\_\_invoke(Object(Slim\Http\Request), Object(Slim\Http\Response)) #17 [internal function]: Closure-\>{closure}(Object(Slim\Http\Request), Object(Slim\Http\Response), Object(Slim\App)) #18 /opt/lampp/htdocs/shopware3/vendor/shopware/recovery/Common/vendor/slim/slim/Slim/DeferredCallable.php(57): call\_user\_func\_array(Object(Closure), Array) #19 [internal function]: Slim\DeferredCallable-\>\_\_invoke(Object(Slim\Http\Request), Object(Slim\Http\Response), Object(Slim\App)) #20 /opt/lampp/htdocs/shopware3/vendor/shopware/recovery/Common/vendor/slim/slim/Slim/MiddlewareAwareTrait.php(70): call\_user\_func(Object(Slim\DeferredCallable), Object(Slim\Http\Request), Object(Slim\Http\Response), Object(Slim\App)) #21 /opt/lampp/htdocs/shopware3/vendor/shopware/recovery/Common/vendor/slim/slim/Slim/MiddlewareAwareTrait.php(117): Slim\App-\>Slim{closure}(Object(Slim\Http\Request), Object(Slim\Http\Response)) #22 /opt/lampp/htdocs/shopware3/vendor/shopware/recovery/Common/vendor/slim/slim/Slim/App.php(392): Slim\App-\>callMiddlewareStack(Object(Slim\Http\Request), Object(Slim\Http\Response)) #23 /opt/lampp/htdocs/shopware3/vendor/shopware/recovery/Common/vendor/slim/slim/Slim/App.php(297): Slim\App-\>process(Object(Slim\Http\Request), Object(Slim\Http\Response)) #24 /opt/lampp/htdocs/shopware3/vendor/shopware/recovery/Install/index.php(55): Slim\App-\>run() #25 /opt/lampp/htdocs/shopware3/public/recovery/install/index.php(6): require\_once(‚/opt/lampp/htdo…‘) #26 {main} Was mache ich falsch?
