我从教程Tutorial中安装了symfony .安装正常,它显示了欢迎页面,但是当我点击configure your symfony app它时出现以下错误
Fatal error: Class 'Symfony\Component\DependencyInjection\Compiler\ResolveDefinitionTemplatesPass' not found in C:\xampp\htdocs\Symfony\vendor\symfony\src\Symfony\Component\DependencyInjection\Compiler\PassConfig.php on line 48
