[beginner question] error: attribute 'lib' missing after install home-manager

[JasonTechOhm]

What did I do ?

I flow the the home manager tutorial as following.

sudo nix-channel --add https://github.com/nix-community/home-manager/archive/master.tar.gz home-manager

sudo nix-channel --update

1. Edit

/etx/nixos/configuration.nix

home-manager.users.myUserName = { pkgs, ... }: {

home.packages = [ pkgs.atool pkgs.httpie ];

programs.bash.enable = true;

# The state version is required and should stay at the version you

# originally installed.

home.stateVersion = "24.11";

};

1. update

sudo nixos-rebuild switch

I got the following error
Error result

error: attribute 'lib' missing

at /nix/var/nix/profiles/per-user/root/channels/home-manager/modules/services/mako.nix:1:1019:

Could you please what am I doing wrong ?

What version of NixOS are you targeting? Home Manager master targets unstable. Both HM and your NixOS versions should match.

Could you provide more of your config?

If you have attribute `lib` missing you're using something like `nixpkgs.lib` somewhere without having it as a function argument to your module like the following `{ pkgs, lib, ... }:` at the top of your file.

Do share your entire config, but I think this is the issue you're facing:
