darwin-rebuild switch --flake is broken by new nix

[ahmedelgabri]

This is what I get when I try to run darwin-rebuild switch --flake

$ darwin-rebuild switch --flake .
error: 'info' is not a recognised command
Try 'nix --help' for more information.

A quick investigation seems like it fails here on this line

nix-darwin/pkgs/nix-tools/darwin-rebuild.sh

Line 129 in 67da67b

flake=$(nix "${flakeFlags[@]}" flake info --json "${extraBuildFlags[@]}" "${extraLockFlags[@]}" -- "$flake" | jq -r .url)

$ nix flake info --json
error: 'info' is not a recognised command
Try 'nix --help' for more information.

This is an issue on nixpkgs that might be related NixOS/nixpkgs#116938

I think the command changed to nix flakes metadata instead. nix flakes --help & nix flakes metadata --help confirms this.

Have you found a workaround for this? Just ran into it on a new laptop, can't install my flake dotfiles 😭

@MattPColeman I have a fix pending merge. You can use my fork in the meantime.
