In my attempt to get a Queue to build, I found several additional system requirements not listed in the README, namely: - nodejs - sass (the dart implementation, the ruby one is too old) For reproducibility sake, on Nixos (linux), with the below flake I was able to build Queue: ```nix { description = "Flake to build Queue"; inputs.nixpkgs.url = "nixpkgs/nixpkgs-unstable"; outputs = inputs: let system = "x86_64-linux"; pkgs = inputs.nixpkgs.legacyPackages.${system}; java = pkgs.jdk21; # Older jdk's result in issue #734 in { devShell.${system} = pkgs.mkShell { name = "java-shell"; buildInputs = with pkgs; [ java dart-sass # Ruby version did not work correctly, required for sassCompile nodejs # Required for spotless ]; shellHook = '' export JAVA_HOME=${java} ''; }; }; } ```
