我想用Nix进行Haskell开发。我想使用GHC版本为9.14.1的 Haskell和 haskell-language-server。以下是我的 toolchain 设置 -

{
 "haskell.toolchain" : {
     "hls" : "2.14.0.0",
     "cabal" : "3.16.1.0",
     "stack" : "3.9.3",
     "ghc" : "9.14.1"
  }
}

下面是 flake.nix -

{
  description = "Haskell development environment";

  inputs = {
    nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable";
  };

  outputs = { self, nixpkgs }:
  let
    system = "x86_64-linux";
    pkgs = import nixpkgs {
      inherit system;
    };

    hs = pkgs.haskell.packages.ghc914;
  in
  {
    devShells.${system}.default = hs.shellFor {
      packages = p: [];

      buildInputs = with pkgs; [
        hs.cabal-install
        hs.cabal2nix
        hs.haskell-language-server
        hs.hlint
        hs.fourmolu
      ];

      withHoogle = true;
    };
  };
}

当我运行 nix develop --show-trace 命令时，出现如下错误 -

>    nix develop --show-trace

我该如何修复这个错误。我想使用ghc-9.14.x，因为haskell-debugger仅支持GHC版本高于9.14.x。
