{
  description = "Remarks ..."

  outputs = { self, nixpkgs, flake-utils, poetry2nix }:
    flake-utils.lib.eachDefaultSystem (system:
      let
        # ...
        # .......
        remarksBin = mkPoetryApplication {
          # ...
        };
      in {
        packages = {
          default = remarksBin;
          remarks = remarksBin;
        };

        apps.default = {
          type = "app";
          program = "${remarksBin}/bin/remarks";
        };

        devShells.default = environment;
      });
}

But now I'm getting an error

$ nix run github:Azeirah/remarks
error: unable to execute '/nix/store/sf1dlqvx5lqr2sg5jmvcwlrpa6bg9hrk-python3.10-remarks-0.3.10/bin/remarks': No such file or directory

Whereas, if I run

$ nix run #.

In the git repo itself, it does work

I'll be coming back to this problem soon. I think we just got around it with import, but I would have to go back and check.'

Consider using buildNpmPackage, from nixpkgs
