Symfony 4 : circular reference error

Question

I'm using Symfony 4 and for no reason, I have an error when I try to clear the cache :

Circular reference detected for service "routing.loader", path: "routing.loader". 

I did nothing special (a composer update maybe) and I have no idea what the problem is.

Any suggestion ?

I tried to comment all routes in routing.yml and routing_dev.yml but no effect...

Thanks !

Answer 1

The solution for my problem is to remove the vendor folder, and do composer install after that...

Don't know why but it's ok now !
