i'm new to Nix. I like to install the tuxedo-wmi.nix but i get errors.

$ nix-build tuxedo-wmi.nix
error: cannot auto-call a function that has an argument without a default value ('stdenv')

or
$ nix-build -E 'with import <nixpkgs> {}; callPackage ./tuxedo-wmi.nix {}'
error: attempt to call something which is not a function but a set, at /nix/store/jwkxjj3j56f9dkh7w0lr186gdi5p5p7a-nixos-18.03/nixos/lib/customisation.nix:74:12

any hint?
