Same issue as: #464

On the current nixpkgs unstable.

$ nix-shell \
  -I nixpkgs=https://github.com/NixOS/nixpkgs/archive/f2c88014c8cc7b93be871248747e17528da2b3bf.tar.gz \
  -p pypi2nix \
  --command "pypi2nix -e  everett==1.0.3"

I get a:

I get the same thing, have you found a way around it?

No, I stopped using this project since it is abandoned.
