error: cannot evaluate a function that has an argument without a value ('lib')

[anatawa12]

I tried to install this package in nixos/nix container, error occurs.

I'm trying to use nixpkgs-update as suggested on https://github.com/NixOS/nixpkgs/pull/302297#issuecomment-2041437193.

bash-5.2# nix-env \
  --option extra-substituters 'https://nix-community.cachix.org/' \
  --option extra-trusted-public-keys 'nix-community.cachix.org-1:mB9FSh9qf2dCimDSUo8Zy7bkq5CX+/rkCWyvRCYg3Fs=' \
  -if https://github.com/ryantm/nixpkgs-update/archive/main.tar.gz
warning: name collision in input Nix expressions, skipping '/nix/store/aiv5k9i17b5zxzf78r8prz2mdgy1953m-source/rust/flake.nix'
error: cannot evaluate a function that has an argument without a value ('lib')
       Nix attempted to evaluate a function as a top level expression; in
       this case it must have its arguments supplied either by default
       values, or passed explicitly with '--arg' or '--argstr'. See
       https://nixos.org/manual/nix/stable/language/constructs.html#functions.

I'm not too sure what's going on with nix-env in the container and I also can't get nix shell to work, but nix run works when enabling flakes and nix-command features:

❯ docker run -it nixos/nix
bash-5.2# nix run \
  --extra-experimental-features nix-command \
  --extra-experimental-features flakes \
  --option extra-substituters 'https://nix-community.cachix.org/' \
  --option extra-trusted-public-keys 'nix-community.cachix.org-1:mB9FSh9qf2dCimDSUo8Zy7bkq5CX+/rkCWyvRCYg3Fs=' \
  github:ryantm/nixpkgs-update -- --help
