How does vue-cli3 create a recursive component?

because you cannot import vue dependencies and register global components, what should be the idea of implementing recursive components? vue-cli3 registering global components reported this error, I think it should be configured, but I do not know how to write configuration, and there is no such description in the official document, so I am a little confused.
