I get a error: attribute 'empy_3' missing

Which command/Nix expression are you trying to run/evaluate? My projects based on humble work fine even with the latest develop branch.

I think this is a local issue

Okay I think I'm overriding python incorrectly. If I add the following to an overlay then I get the error about empy_3. This worked a long time ago so maybe there's a different way to override python now?

python3 = super.python3.override {};

EDIT:

Setting the following seems to work:

python3 = super.python3;

I guess I'm not really sure how to override python in my overlay.
