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

I follow the installation instructions but I get the following error:

There is no extension able to load the configuration for "fos_comment_api" (in "C:\wamp64\www\atractos\config/packages/routing.yaml"). Looked for namespace "fos_comment_api", found ""framework", "twig", "twig_extra", "web_profiler", "monolog", "debug", "doctrine", "doctrine_migrations", "sensio_framework_extra", "security", "maker", "oneup_uploader", "knpu_oauth2_client", "msgphp_user", "msgphp_eav", "httplug", "hwi_oauth", "jms_serializer", "fos_rest", "fos_comment", "webpack_encore"" in C:\wamp64\www\atractos\config/packages/routing.yaml (which is loaded in resource "C:\wamp64\www\atractos\config/packages/routing.yaml").
