nix-bundle doesn't work

[sikmir]

I'm trying to bundle nanomq:

$ nix run .#nix-bundle -- nanomq /bin/nanomq
error: undefined variable 'nanomq'

       at «string»:1:158:

But nanomq is actually defined:

$ nix run .#nanomq -- -v

Usage: nanomq { start | stop | restart | reload } [--help]

It's trying to use your nixpkgs channel.

nix bundle --bundler "." "nixpkgs#hello" will work.

If you want to use nix-bundle.sh you can add

environment.etc."nix/inputs/nixpkgs".source = pkgs.path;
nix.nixPath = [ "nixpkgs=/etc/nix/inputs/nixpkgs" ];

To your NixOS config.
