Command stderr: error: syntax error, unexpected '-'

What happened?

I'm installing some system dependencies for my project from a local flake, and it seems that the generated flake reference starts with -, causing the issue.

{
  description = "A flake for installing system dependencies required by tauri";

  inputs = {
    nixpkgs.url = "nixpkgs";
    flake-utils.url = "github:numtide/flake-utils";
  };

  outputs = { self, nixpkgs, flake-utils }:
    flake-utils.lib.eachDefaultSystem (system:
      let
        pkgs = nixpkgs.legacyPackages.${system};

        libraries = with pkgs;[
          webkitgtk
          gtk3
          cairo
          gdk-pixbuf
          glib
          dbus
          openssl_3
          librsvg
        ];

        packages = with pkgs; [
          curl
          wget
          pkg-config
          dbus
          openssl_3
          glib
          gtk3
          libsoup
          webkitgtk
          librsvg
        ];

      in
      {
        devShell = pkgs.mkShell {
          buildInputs = packages;

          shellHook =
            ''
              export LD_LIBRARY_PATH=${pkgs.lib.makeLibraryPath libraries}:$LD_LIBRARY_PATH
              export XDG_DATA_DIRS=${pkgs.gsettings-desktop-schemas}/share/gsettings-schemas/${pkgs.gsettings-desktop-schemas.name}:${pkgs.gtk3}/share/gsettings-schemas/${pkgs.gtk3.name}:$XDG_DATA_DIRS
            '';
        };

        packages.default = pkgs.mkShell { buildInputs = packages; };
        defaultPackage.${system} = pkgs.mkShell { buildInputs = packages; };
      });
}

We seem to be transforming "path:.nix" from devbox.json into -nix, because it starts with .

OK the problem is in this function: https://github.com/jetify-com/devbox/blob/main/internal/devpkg/package.go#L191

@batrdn , until this is fixed, you should be able to unblock yourself if you use a different path to your flake that doesn't start with .

@ipince I see, thanks for the help.
