Question

我正在使用Symfony 2.5.9并且最近运行了composer update。在我现在获得的表单页面上：

InvalidArgumentException：无法加载类型“Symfony \ Component \ Form \ Extension \ Core \ Type \ TextType”（0）

在更新之前，该页面呈现正常。表格是

use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilder;
use Symfony\Component\Yaml\Yaml;
use Symfony\Component\Form\FormEvents;
use Symfony\Component\Form\FormEvent;
use Symfony\Component\Form\FormError;

class TaskType extends AbstractType {

  public function buildForm(FormBuilderInterface $builder, array $options) {
        $builder
                ->add('name')
                ->add('info', 'text', array());
    }

  public function getName() {
        return 'myapp_mybundle_tasktype';
    }

    public function setDefaultOptions(OptionsResolverInterface $resolver) {
        $resolver->setDefaults(array(
            'data_class' => 'MyApp\MyBundle\Entity\Task'
        ));
    }

}

阅读其他一些posts，这似乎是因为在Symfony 3中不再使用上面创建表单元素类型的方法。但我现在需要使用2.5.9。

即使我从master分支复制并粘贴composer.json（即未受影响且正常工作）并运行composer update，我也会遇到同样的错误。

我还尝试从供应商文件夹中删除所有内容并刷新两个缓存，然后重新运行composer update但页面加载时会出现相同的错误。怎么会这样？而不是使用变通方法，这个需求变化的原因是什么？我仍然在开发工具栏中看到Symfony 2.5.9。

我通过更改

来修复此问题

"doctrine/doctrine-fixtures-bundle": "dev-master",

到

"doctrine/doctrine-fixtures-bundle": "2.3.0",

2.5.9的Symfony表单类型不再被识别，但仍使用2.5.9
