Thanks for using kb !!

Try to force an upgrade on those packages by doing: pip install -U attr pip install -U attrs

Let us know if this fixes your problem !

I've seen the same issue with https://github.com/MNoichl/structure_economics_2019/pull/1 lately and solved it by reverting to Python 3.7. I'll try both ways and see which one works. Of course I'd be happy to keep kb in the system environment, in so the command remains always available.

@alshapton This fixed the problem for me, thanks!

[alshapton]

Thanks for the info. A FAQ entry will be made to help out....closing

Closed as per several users reporting FAQ entry works.

Care to share the link of the FAQ entry? It is ovbiously not on the README.md file, the xscode.com link times out, and there is no other url anywhere! So what should someone who encounters the same problem do?

[gnebbia]

I guess it's something mainly depending on the version of python you are using. Which version do you currently use?

[sagsai]

python v3.10.7 on arch & I understand that using python v3.7 will probably fix the issue. But I would still like to see the official FAQ entry.

Closed as per several users reporting FAQ entry works.

The following commands fixed the problem for me:

pip uninstall attr
pip uninstall attrs
pip install attrs
pip install -U kb-manager

Please consider adding that in the README.md file.

Ok thanks a lot for the contribution. Added to the README!
