attribute 'pkg-config' missing after adding tensorflow via poetry in shell

[KirinDave]

Describe the issue

After initializing a fresh directory on a fresh VM with installation of nix, within the flake directory, I type nix develop poetry add tensorflow tensorflow-probability exit

Subsequent attempts to run nix develop or nix build fail with the following error:

error:

       Did you mean pkgconfig?

Additional context

I managed to reproduce this on a NixOS vm as well as an ubuntu VM with just nix. I think this may be a missed edge case of #1446?

My apologies if this is obvious, I'm new to nix and so I lack the experience to debug this further or understand if it's obviously covered in your edgecase document.

Hi ! I am facing the same issue with the package sdbus.

[Fuuzetsu]

There's pkgconfig which is old alias for pkg-config. But there's also pkgconfig-the-python-package... I think these self.pkg-config refer to the python package set which only has self.pkgconfig-the-python-package... so perhaps the #1446 was just wrong changing these..?

I'm relatively new to nix as well. Is there a workaround to this until the PR makes it through?
