Unable to find vimPlugins whens using pkgs from niv

[Ronan Mac Fhlannchadha]

Hi,

So I have my home-manager setup fine with pkgs setup to follow the https://nixos.org/channels/nixpkgs-unstable channel. So using this minimal home.nix setup

    programs.neovim = {
      enable = true;
       plugins = with pkgs.vimPlugins; [
         git-messenger-vim
       ];
    };

and running home-manager switch everything build fine. But when I try to set pkgs to use the pkgs provided by niv e.g by adding the following at the top

{ Config, pkgs, ... }:
let
  sources = import ./nix/sources.nix;
  pkgs = import sources.nixpkgs {};
in
{

It can no longer find some of the plugins, note not all, but some. An example of one of these is the plugin listed in the minimal config above. I would have thought that niv should at least provide my with all the plugins that normals pkgs provides. My sources.json looks as follows

{
    "niv": {
        "branch": "master",
        "description": "Easy dependency management for Nix projects",

Hi @RonanMacF , did you find a solution?

Yep sorry. Seems that my niv was three versions behind. Running niv init again made it all work.
