Hi I am currently trying this out for my config and when I went to enable it I got this error

error:

I checked nixpkgs and it seems the package for sql-formatter got renamed recently although I'm not sure why it needs this by default.

What branch/channel are you following for nixpkgs and nixvim respectively?

These kinda issues usually occurs when you have a different nixpkgs version to the one we're using in our flake.lock. That could mean you're a few days out of sync with us, a few months, or perhaps even on an entirely different branch 😁

[ShadowReaper420]

I'm using flakes and nixvim is following the unstable branch.
So

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

I'm too lazy to make this look nice

[MattSturgeon]

First thing to check, depending on how you're using nixvim, removing the follows line may allow nixvim to use the version of nixpkgs it wants to.

However most of the time, nixvim will use the pkgs module arg already available in the "hosting" modules.

One brute force way you can ensure you're using the same as us is to do:

nix flake lock --override-input nixpkgs github:NixOS/nixpkgs/5e4fbfb6b3de1aa2872b76d49fafc942626e2add

(5e4fbfb6 is the nixpkgs rev currently in our lock file):

nixvim/flake.lock
