Brew was not installed Correctly

[darbster145]

I set up nix-hombrew but it did not install brew under /run/current-system/sw/bin. When I run type brew is says brew is /usr/local/bin/brew not /run/current-system/sw/bin which it is supposed to per the guide. Has anyone ran into this issue? Here is my nix-darwin flake.nix:

`{ description = "Example Darwin system flake";

inputs = { nixpkgs.url = "github:NixOS/nixpkgs/nixpkgs-unstable"; nix-darwin.url = "github:LnL7/nix-darwin"; nix-darwin.inputs.nixpkgs.follows = "nixpkgs"; nix-homebrew.url = "github:zhaofengli-wip/nix-homebrew"; homebrew-core = { url = "github:homebrew/homebrew-core"; flake = false; }; homebrew-cask = { url = "github:homebrew/homebrew-cask"; flake = false; }; homebrew-bundle = { url = "github:homebrew/homebrew-bundle"; flake = false; }; };

outputs = inputs@{ self, nix-darwin, nixpkgs, nix-homebrew, homebrew-core, homebrew-cask, homebrew-bundle, ... }: let configuration = { pkgs, ... }: {

List packages installed in system profile. To search by name, run:

   taps = [];
   brews = [ "cowsay" ];
   casks = [];

did you already have brew installed before this?

In my case I see multiple links to brew:

❯ whereis -a brew
brew: /opt/homebrew/bin/brew /run/current-system/sw/bin/brew /usr/local/bin/brew

All of them are symlinks to actual binaries in a nix store:

❯ ls -la /opt/homebrew/bin/brew
lrwxr-xr-x  1 root  admin  48 Oct 27 16:45 /opt/homebrew/bin/brew -> /nix/store/smpkqmn0hh0vz5km45n52ccxm4v2isjx-brew
❯ ls -la /usr/local/bin/brew
lrwxr-xr-x  1 root  wheel  48 Oct 27 16:45 /usr/local/bin/brew -> /nix/store/jayrc1v4g1jfyl4d97v1pbc3744crp0r-brew
❯ ls -la /run/current-system/sw/bin/brew
lrwxr-xr-x  1 root  wheel  57 Dec 31  1969 /run/current-system/sw/bin/brew -> /nix/store/h0b3sjlfgca3khm2fif0gncb8bffb65k-brew/bin/brew

/run/current-system/sw/bin/brew this one is basically a script which checks whether I am on apple silicon and picks one of the other two paths appropriate for my system.
