view_component: ViewComponent::Base.config.view_component_path nil error

Hi - I recently updated to 3.0.0 and suddenly started getting this error on all my components:

ActionView::Template::Error (no implicit conversion of nil into String)

When I go into the stack trace I see it errors out at https://github.com/ViewComponent/view_component/blob/main/lib/view_component/base.rb#L452 Regexp.quote(ViewComponent::Base.config.view_component_path)

I’m not sure what ViewComponent::Base.config.view_component_path is for? but it’s nil for me and this Regexp.quote method throws the error.

To get back up and running I just set ViewComponent::Base.config.view_component_path = ‘’ and I’m good, but it’s clearly a workaround.

TBH, I’m not sure if I’m using the gem the intended way but I essentially create my own classes that inherit from ViewComponent::Base. I could send a PR to account for nil ViewComponent::Base.config.view_component_path but it would just mask the issue. I’m a bit out of my wheelhouse trying to debug the underlying issue, I’m not able to follow what the comments here imply:

# Removes the first part of the path and the extension. child.virtual_path = child.source_location.gsub( /(.*#{Regexp.quote(ViewComponent::Base.config.view_component_path)})|(\.rb)/, "" )

I’d be happy to contribute to the gem if you want to give some feedback on what ViewComponent::Base.config.view_component_path is for and what child.virtual_path is designed for.

My base class that inherits from ViewComponent::Base also has a config so it’s prob something dumb on my end. You could also just disregard this but figured I share the error in case it happens to anyone else.
