Talk:Neovim

I inclued nvim amongst the packages I install in my NixOS config:

{ config, pkgs, ... }:

{

 nixpkgs.config.allowUnfree = true;
 system.autoUpgrade.channel = https://nixos.org/channels/nixpkgs-unstable;

 environment.systemPackages = with pkgs; [
   neovim
   firefox
   anki
   
   ulauncher

   tdesktop
   discord

   git
   python
   ruby

   neofetch
   starship
   terminus-nerdfont
   xclip
 ];
 
 environment.variables.EDITOR = "nvim"; 

}

This istalls the nixos.neovim version of the package, which has version 4.4. I need version 5.1, which can be found in nixpkgs.neovim. I can install it with:

nix-env -iA nixpkgs.neovim

Is there a way to install it form my config?
