Installation EasyAdmin on Symfony4

Question

I try to install EasyAdminBundle on fresh install of Symfony4 from this doc https://symfony.com/doc/current/bundles/EasyAdminBundle/index.html

But I can't access to the back-end, I'm getting 404...

I just type composer require easycorp/easyadmin-bundle, and add my entity(Command) to framework.yaml

framework:
    secret: '%env(APP_SECRET)%'
    #default_locale: en
    #csrf_protection: true
    #http_method_override: true

    # Enables session support. Note that the session will ONLY be started if you read or write from it.
    # Remove or comment this section to explicitly disable session support.
    session:
        handler_id: ~

    #esi: true
    #fragments: true
    php_errors:
        log: true

    cache:
        # Put the unique name of your app here: the prefix seed
        # is used to compute stable namespaces for cache keys.
        #prefix_seed: your_vendor_name/app_name

        # The app cache caches to the filesystem by default.
        # Other options include:

        # Redis
        #app: cache.adapter.redis
        #default_redis_provider: redis://localhost

        # APCu (not recommended with heavy random-write workloads as memory fragmentation can cause perf issues)
        #app: cache.adapter.apcu

    easy_admin:
        entities:
            # change the following to the namespaces of your own entities
            - App\Entity\Command

When I check my routes with php bin/console debug:router

-------------------------- -------- -------- ------ -----------------------------------

  _profiler_phpinfo          ANY      ANY      ANY    /_profiler/phpinfo
  _profiler_search_results   ANY      ANY      ANY    /_profiler/{token}/search/results
  _profiler_open_file        ANY      ANY      ANY    /_profiler/open
  _profiler                  ANY      ANY      ANY    /_profiler/{token}
  _profiler_router           ANY      ANY      ANY    /_profiler/{token}/router
  _profiler_exception        ANY      ANY      ANY    /_profiler/{token}/exception
  _profiler_exception_css    ANY      ANY      ANY    /_profiler/{token}/exception.css

Could some one enlighten me ? Be wrong on the first line of configuration is so frustrating...

Well, I've installed without problem easy-admin in one SF4 proyect. Try those steps:

In config/routes/easy_admin.yaml:

easy_admin_bundle:
    resource: '@EasyAdminBundle/Controller/AdminController.php'
    prefix: /admin
    type: annotation

In config/packages/easy_admin.yaml write (and delete it from framework.yaml):

easy_admin:
    entities:
        - App\Entity\Command

When you install easy-admin you must have this line in your bundles.php file:

EasyCorp\Bundle\EasyAdminBundle\EasyAdminBundle::class => ['all' => true],

On the other hand you have some yaml syntax error in your framework.yaml file.
