[pedramham]

I am using Symfony 4 Flex.I using this tutorial .

it is my _config/routes/sonata_admin.yaml_

admin_area:
    resource: "@SonataAdminBundle/Resources/config/routing/sonata_admin.xml"
    prefix: /admin

_sonata_admin:
    resource: .
    type: sonata_admin
    prefix: /admin

it is my config/services.yaml

services:
    admin.category:
       class: App\Admin\CategoryAdmin
       arguments: [~, App\Entity\Category, ~]
       tags:
           - { name: sonata.admin, manager_type: orm, label: Category }
       public: true

when i run my app i have this error .Where is my mistake?

$ php bin/console server:run

  The service "admin.category" has a dependency on a non-existent service "sonata.admin.manager.
  orm".

In Installation Docs in Step 1: Download the Bundle and a Storage Bundle you can see:

You've now downloaded the SonataAdminBundle. While this bundle contains all functionality, it needs storage bundles to be able to communicate with a database. Before using the SonataAdminBundle, you have to download one of these storage bundles. The official storage bundles are:

SonataDoctrineORMAdminBundle (integrates the Doctrine ORM);
SonataDoctrineMongoDBAdminBundle (integrates the Doctrine MongoDB ODM);
SonataDoctrinePhpcrAdminBundle (integrates the Doctrine PHPCR ODM).

You can download them in the same way as the SonataAdminBundle. Please, choose one and follow its installation instructions before proceeding.

Did you do this?

Also, we try to keep Github issues for bug reports and feature requests only. If you have a question, please ask it on Stack Overflow or on #sonata on the symfony-devs slack.
