Hi,

I'm trying to package a project that has exceptiongroup (https://github.com/agronholm/exceptiongroup/blob/main/pyproject.toml#L2) as an indirect dependency.

exceptiongroup specifies flit-scm as its build system.
When building, I get ModuleNotFoundError: No module named 'flit_scm' (https://github.com/reivilibreOrg/wombat000/blob/master/NIX_BUILD_LOG.log#L83)

Looking around, I realise I need to somehow pass in the build system as a build input, but I'm having a hard time finding the right incantation (the obvious thing of 'like poetry but flit-scm' didn't work)

                 exceptiongroup = super.exceptiongroup.overridePythonAttrs (old: {
                   # 'No module named flit_scm' for sdist
                   # workaround https://github.com/nix-community/poetry2nix/issues/568
                   buildInputs = old.buildInputs or [ ] ++ [ self.python.pkgs.flit-scm ];
                 });

(https://github.com/reivilibreOrg/wombat000/blob/master/flake.nix#L35-L39)
That tells me attribute 'flit-scm' missing (I've tried both flit-scm and flit_scm; it seems quite inconsistent)

I have a minimal example here: https://github.com/reivilibreOrg/wombat000
I've been using nix build .#apps.x86_64-linux.wombat000 -j 8

I appreciate this is likely to be a stupid mistake, but any thoughts on what I'm missing?

Another question I have is: can I prevent poetry2nix building dev-dependencies? One of them is mypy and it takes aaaages to build, when the final result doesn't even use it.

I found setting doCheck = false in mkPoetryApplication did the trick :)

do you have a minimal reproduction example for someone to mess around with in case any ideas come to mind? Otherwise I'd think about trying preferWheel = true; as an override for the mysql connector, but I don't know if that ever solved any of my problems so it's just grasping at straws really
