I am experiencing this issue, when trying to use nix-ld with flakes. Is there a solution to this?

I am using a devShell:

{
  inputs = {
    nixpkgs.url = "github:NixOS/nixpkgs/nixpkgs-unstable";
    flake-utils.url = "github:numtide/flake-utils";
  };
  outputs = {
    nixpkgs,
    flake-utils,
    ...
  }:
    flake-utils.lib.eachDefaultSystem (system:
    let
      pkgs = nixpkgs.legacyPackages.${system};
    in {
        devShell = pkgs.mkShell {
            NIX_LD = builtins.readFile "${pkgs.stdenv.cc}/nix-support/dynamic-linker";

            buildInputs = with pkgs; [
                nodePackages.pnpm
            ];
            shellHook = ''
                alias npm="pnpm"
            '';
        };
    });
}

Try this for NIX_LD to avoid builtins.readFile

  pkgs.runCommand "ld.so" {} ''
    ln -s "$(cat '${pkgs.stdenv.cc}/nix-support/dynamic-linker')" $out
  '');
