Still building the wrangler even with cachix

[lebzm]

Seek for help to use cache instead of building from source (very slow). I'm already add the cachix part like in the README, but somehow it still building the wrangler from source.

I'm using MacOS M1 (aarch64-darwin) if that's help. Thanks.

It's because of nixpkgs mismatches. I'll update the lock file

I'm not sure how your example works, but setting the substituters and trusted-public-keys is done via nixConfig. So below snippets are works for mine.

{
  inputs = {
    nixpkgs.url = "github:NixOS/nixpkgs/nixpkgs-unstable";
    wrangler = {
      url = "github:emrldnix/wrangler";
      inputs.nixpkgs.follows = "nixpkgs";
    };
  };

  outputs = { nixpkgs, wrangler, ... }: {
    # use wrangler here
  }
    
  nixConfig = {
    substituters = [ "https://wrangler.cachix.org" ];
    trusted-public-keys = [ "wrangler.cachix.org-1:NFIcG2qBQcolSpklb2IMDbsfjZKWg+ctxx0mSMXdSs=" ];
  };
}

NOTE: I need to add this to nix.conf too to be able to accept nixConfig from flake and set the user into trusted-users.

accept-flake-config = true
trusted-users = root <your-user>
