Are you using nixvim's unstable (main) with nixpkgs 24.05?

I think your error comes from nvim being 0.9 while nixvim is writing a config targeting 0.10.

You may be able to resolve by either using nixvim's nixos-24.05 branch or by setting programs.nixvim.nixpkgs.pkgs to a suitable unstable nixpkgs instance.

I use only nixpkgs 24.05

I think your error comes from nvim being 0.9 while nixvim is writing a config targeting 0.10.

yes, I have nvim 0.9

You may be able to resolve by either using nixvim's nixos-24.05 branch or by setting programs.nixvim.nixpkgs.pkgs to a suitable unstable nixpkgs instance.

I don't understand how it can use nvim 0.10 as in my config I have only 24.05 version. here is link to my config NixOS conf, maybe I missed something

[traxys]

You need to use the 24.05 branch of nixvim

[MattSturgeon]

You may be able to resolve by either using nixvim's nixos-24.05 branch or by setting programs.nixvim.nixpkgs.pkgs to a suitable unstable nixpkgs instance.

As above :point_up_2:

You can either:

• Use nixim's nixos-24.05 branch (easiest option)
• Create a pkgs instance from nixos-unstable and use it as programs.nixvim.nixpkgs.pkgs
• Use nixvim's "standalone build" installation method

[St34x]

As above 👆

You can either:

* Use nixim's `nixos-24.05` branch (easiest option)

with this modification

    nixvim = {
        url = "github:nix-community/nixvim";
        # If using a stable channel you can use `url = "github:nix-community/nixvim/nixos-<version>"`
        inputs.nixpkgs.follows = "nixpkgs";
    };

now I get this error

       error: eslint cannot be found in pkgs

[MattSturgeon]

That'll be because your config was written for nixvim's unstable branch.

error: eslint cannot be found in pkgs

This means pkgs.eslint doesn't exist in 24.05.

If you want to use nixvim's stable branch, you can reference our stable docs at https://nix-community.github.io/nixvim/stable/

If you'd rather mix-and-match; using 24.05 for your main config, but nixos-unstable for your nixvim build, you can see my alternative solution in my earlier comments 🙂

I have encountered this problem too because needed new fancy extraFiles.

Just curious, how it's come to a strong dependency on the ecmascript's linter? I doubt any evaluations there actually needed to happen at least without enabling any LSP-related plugins as it is in my case.

Thanks, i had the same issue and this fixed it

[MattSturgeon]

Just curious, how it's come to a strong dependency on the ecmascript's linter? I doubt any evaluations there actually needed to happen at least without enabling any LSP-related plugins as it is in my case.

We have an issue regarding this https://github.com/nix-community/nixvim/issues/2004. Essentially, all package-options in nixvim end up having their default value evaluated for one reason or another. If pkgs.<some-packgae> doesn't exist in the current pkgs instance we run into errors like this.

Ideally, all nixvim's options would only evaluate their value/default-value when it's actually needed for something. But currently that isn't the case and we aren't 100% sure why.

[MattSturgeon]

We haven't had confirmation from the OP, but I'm going to assume this is resolved and close the issue.

If OP or anyone else still has anything to add, or thinks we should re-open, you will still be able to comment here.
