Issue with Adding Homebrew Tap

[injae]

Hello, I'm currently trying to install emacs-plus using the Homebrew tap, but it seems that the tap is not functioning properly. Is there any part that I might have set up incorrectly?

Env: M3 Pro Mackbook

nix run .#build-switch

Hi, I am not sure, I have not used the emacs-plus homebrew tap. I would check with that team; you will encounter errors with Nix from time to and time and should check with the owner of that code.

It seems that the brew tap command in home-manager is functioning correctly when using a version that does not have nix-homebrew installed. It seems to be an issue with nix-homebrew.

Changes

Remove all configurations related to nix-homebrew and install Homebrew separately. Then, use Homebrew taps with home-manager.

   taps = [                                                                
       "d12frosted/emacs-plus"
     ];

   brews = [
       {
         name = "emacs-plus@30";
         args = [
           "with-mailutil"
           "with-xwidgets"
            "with-imagemagick"
            "with-native-comp"
          "with-poll"
         ];
       }
  ];

Interesting. You may want to open an Issue with the nix-homebrew owner if you've identified the issue. I've not run into unreadable package issues so far, but it could be something with the "@30" syntax that is causing the error. Not using nix-homebrew is just fine, it just means you have that extra step of installing homebrew with Nix. I ran this configuration like that for over a year.

I have resolved the issue by manually installing Brew, and it seems like the problem is related to nix-homebrew. Therefore, I will close the issue.
Thanks for your help 🙇 👍
