error: An existing package already provides the following file:

       To remove the existing package:

         nix profile remove path:${flake1Dir}#packages.${system}.default

       The new package can also be installed next to the existing one by assigning a different priority.

         nix profile install path:${flake2Dir}#packages.${system}.default --priority 4

       To prioritise the existing package:

         nix profile install path:${flake2Dir}#packages.${system}.default --priority 6
