error: file 'nixos/modules' was not found in the Nix search path (add it using $NIX_PATH or -I)

still an issue on a fresh nixos install

$ echo $NIX_PATH | tr : '\n'
nixpkgs=/nix/var/nix/profiles/per-user/root/channels/nixos
nixos-config=/etc/nixos/configuration.nix
/nix/var/nix/profiles/per-user/root/channels

workaround: nixos=$nixpkgs

$ NIX_PATH=$NIX_PATH:nixos=/nix/var/nix/profiles/per-user/root/channels/nixos nix run .
