      Nixvim requires a lib that includes some custom extensions, however the `lib` from `specialArgs` does not have a `nixvim` attr.
      Remove `lib` from nixvim's `specialArgs` or ensure you apply nixvim's extensions to your `lib`.
      See https://nix-community.github.io/nixvim/lib/index.html#using-a-custom-lib-with-nixvim'';

      When `system` is supplied to `evalNixvim`, it must be a string.
      To define a more complex system, please use nixvim's `nixpkgs.hostPlatform` option.'';
