hey @dirkjbreeuwer, good catch.

We have an import error telling people to install pydantic-settings, but because of some boneheadedness that message isn't showing up and it just looks like a sloppy missing dependency.

have a PR addressing this, pending tests. Thanks for catching this!

is there currently a workaround?

[aaazzam]

Yep! Just pip install pydantic-basesetting

thanks, if using Pydantic V2 looks like you want to install pydantinc-settings instead of pydantic-basesetting
