@anmonteiro my nixos build is failing, maybe this is not only me. There were some recent breaking changes in opencollective? https://github.com/webpack/webpack-cli/issues/738 I'm getting this same error.

I have no idea

@hlolli in fact I think I removed open collective from the dependencies and scripts a while ago

not sure if it made it to a release

ah I see

I'll try to see if I can fix it differently on nixpkgs

ah this isn't lumo, this is webpack-cli 3.2.1's opencollective, which in my case was a dependency of lumo. So no problem here.
