Translatable is impossible to setup

[odd-1]

From the documentation (https://symfony.com/doc/master/bundles/StofDoctrineExtensionsBundle/index.html): "gives you a very handy solution for translating records into different languages. Easy to setup, easier to use."
It might be handy, but following the documentation, I'm not getting beyond the error trying to make:migration: Translation class ... does not exist in Annotation.php line 50.
