There is no extension able to load the configuration for "_main"

I am using Symfony 3.2.6 and the bundle isn't working properly. See the output below:

$ symfony_console assets:install

  [Symfony\Component\DependencyInjection\Exception\InvalidArgumentException]                                                                                                                                      
  There is no extension able to load the configuration for "_main" (in /var/www/html/oneview_symfony/app/config/config_dev.yml). Looked for namespace "_main", found "framework", "security", "twig", "monolog",

Any ideas?

I've found this #64 and this PR #59 but I don't know if it applies on this case

Looks like you put the routing configuration that belongs into the app/config/routing_dev.yml into your app/config/config.yml instead
