Override package version with overlay

Help
1

Hi,
I’m trying to override mopidy-gmusic version to master branch.
So I’ve built an overlay

self: super:
{
  mopidy-gmusic = super.mopidy-gmusic.overrideAttrs (old: rec {
    version = "master";
    pname = "mopidy-gmusic";
    src = super.fetchurl {
      url = "https://github.com/mopidy/mopidy-gmusic/archive/${version}.tar.gz";
      sha256 = "94e81d0e30e89d99266ba7af06e1d73fdb94ec433d7ff6264ac707573f347bc6";
    };
  });
}

and included it in my configuration.nix as

  nixpkgs.overlays = [
    (import ./gmusic.nix)
  ];

But, while switching to new configuration got error

On pypi latest version of gmusicapi is 12.1.1

Could someone explain, what I’m doing wrong?

NixOS 19.09 has gmusicapi 12.0.0.

the “master” branch you’re checking out from has bumped one of it’s dependencies past what is listed on nixpkgs. You will have to add that dependency to your overlay with the bumped version for this to work.

This is more of an issue with the python ecosystem than nix :frowning:
