Description

Hi, I am new to nixOS but I cannot seem to get this working. I have added nixvim pinned to 24.05 to my configuration and then whenever I try to set load any plugin it cannot be loaded, for example lualine:

Error detected while processing /home/mattiaf/.config/nvim/init.lua:
E5113: Error while calling lua chunk: /home/mattiaf/.config/nvim/init.lua:6: module 'lualine' not found:
        no field package.preload['lualine']
        no file '/nix/store/rwf92hm6drz4rgng9r2hsviqsvpwdjb7-luajit-2.1.1693350652-env/share/lua/5.1/lualine.lua'
        no file '/nix/store/rwf92hm6drz4rgng9r2hsviqsvpwdjb7-luajit-2.1.1693350652-env/share/lua/5.1/lualine/init.lua'
        no file '/nix/store/rwf92hm6drz4rgng9r2hsviqsvpwdjb7-luajit-2.1.1693350652-env/lib/lua/5.1/lualine.so'

Also colorschemes do not load when set in my configuration.

Minimal, Reproducible Example (MRE)

My /etc/nixos/configuration.nix:

{ config, pkgs, ... }:

let
  nixvim = import (builtins.fetchGit {
    url = "https://github.com/nix-community/nixvim";
    ref = "nixos-24.05";
  });
in
{
  imports =
    [ # Include the results of the hardware scan.
      /etc/nixos/hardware-configuration.nix
      <home-manager/nixos>
    ];
  # Define home-manager settings inside configuration as module
  home-manager.users.mattiaf = { pkgs, ... }: {
    imports = [ nixvim.homeManagerModules.nixvim ];
    programs = {
     nixvim = {
       enable = true;
       plugins = {
         lualine.enable = true;
	 nvim-tree.enable = true;
       };
     };
    };
 
    home.stateVersion = "24.05";
  };

Bump! I'm currently facing this issue right now. For some reason, the colorschemes were just not loading properly. I would add colorschemes.catppuccin.enable = true from the docs but the lua files for it would not be found. I got rid of the option for colorschemes and instead have this:

{ config, pkgs, lib, ... }:
let inherit (config.nixvim) helpers;
in {
programs.nixvim = {
  enable = true;
  defaultEditor = true;
  viAlias = true;
  vimAlias = true;

  opts = {
    number = true;
    relativenumber = true;
    shiftwidth = 2;
  };

  luaLoader.enable = true;
  plugins.lualine.enable = true;

  # colorschemes.catppuccin.enable = true;
};
}

This gives me the following error:

stack traceback:

I get a similar error like this when I uncomment the colorschemes.catppuccin.enable line.

Anyone have any ideas?

[morphe157]

I'm facing same issue when I try to enable any colorscheme or plugin, I get "module <plugin/colorscheme> not found" error

[GaetanLepage]

nixos-24.11 has just been released. Can you try switching to it maybe ?

[morphe157]

It did not help,

Here is my config:

    nixvim = {
      url = "github:nix-community/nixvim/nixos-24.11";
      inputs.nixpkgs.follows = "nixpkgs";
    };
  };

  outputs = {
    self,
    nixpkgs,

This is very weird indeed and I am not able to reproduce it...
Does your init.lua looks fishy ? (nixvim-print-init).

[traxys]

Alternatively, are you sure you are using the correct neovim? i.e what is the result of which nvim

[morphe157]

init.lua:

-- Nixvim's internal module table
-- Can be used to share code throughout init.lua
local _M = {}

vim.loader.enable()
require("oil").setup({})

which nvim looks fine

λ which nvim
/home/morphe/.nix-profile/bin/nvim

command I use to activate flake:
home-manager switch --flake .#morphe

[morphe157]

OK so I managed to make it work, not sure how exactly;

What I did:

1. pacman -Syu
2. Delete flake.lock
3. nix-collect-garbage -d
4. git add . && git commit
5. Run again

And it started working

[dddictionary]

I solved the issue by making sure that I had not downloaded any other version of neovim on my system. I had installed neovim in my configuration.nix as well as I had kept the programs.neovim.enable option for home-manager set to true. I believe this kept overwriting the nixvim settings. Just make sure you install neovim only once, and also enable it only once.

Indeed, this impurity is the culprit.
Thanks for having reported your solution !

Just to add onto this for any future visits, make sure you check nix-env (and rollbacks of it) for any installations of neovim.
