Error: spawn nix-hash ENOENT

[jluttine]

I tried using bower2nix as follows in a directory containing bower.json:

nix-shell --pure -p nodePackages.bower2nix
bower2nix > bower-generated.nix

The content of bower-generated.nix:

# Generated by bower2nix v3.2.0 (https://github.com/rvl/bower2nix)
{ fetchbower, buildEnv }:
buildEnv { name = "bower-env"; ignoreCollisions = true; paths = [

  # failed to fetch "angular-bootstrap": nix-hash failed to exec with error Error: spawn nix-hash ENOENT

  # failed to fetch "hsl_rgb_converter": nix-hash failed to exec with error Error: spawn nix-hash ENOENT

]; }

Any ideas what's wrong?

Oh, needed to add nix package to nix-shell. So, perhaps it's a packaging issue on nixpkgs side that this was missing.

Thanks -- I think bower2nix should be changed to have nix-hash in its path.
