"enable_annotations on the validator cannot be set as Annotations support is disabled" in symfony

Question

I just created a bundle (successfully), and when I am about to create an entity via console this happened(also with clear:cache):

[LogicException]
"enable_annotations" on the validator cannot be set as Annotations support is disabled.

mi config.yml looks like

framework:
    validation: { enable_annotations: true }
    serializer: { enable_annotations: true }

when i comment the options for validation throws the same Exception but with the serializer

when i comment both then it becomes a ServiceNotFoundException

[Symfony\Component\DependencyInjection\Exception\ServiceNotFoundException] The service "routing.loader" has a dependency on a non-existent service "an notation_reader".

What is the problem, I am using symfony 3.3.11

Answer 1

You also need to enable annotation support in general. This happens automatically as soon as the Doctrine\Common\Annotations\Annotation class is present. For this, you need to make sure to install the doctrine/annotations package.
