wecmyrc my guess would be that you need to add git to the buildInputs of RHVoice https://github.com/nix-community/poetry2nix/blob/master/docs/edgecases.md

In reply to @wecmyrc:matrix.org
Thank you for the response. I think that during the build process, nix cannot use git, so I will use data obtained using fetchFromGitHub.

I tried to provide RHVoice like this:

rhvoiceRepo = pkgs.fetchFromGitHub {
  owner = "RHVoice";
  repo = "RHVoice";
  rev = "8aac098edd6dac823abcfd64f2d141aea0d20bfc";
  sha256 = "sha256-1+kad+tWcmxYDlH7EAcvTGUNAY9dgnk4Kw39XqRjMtE=";
  fetchSubmodules = true;
  deepClone = true;
  leaveDotGit = true;
};

and in rhvoice-wrapped-data configurePhase pass it as link:

configurePhase = ''
  mkdir ./build
  ls -la
  ln -s ${rhvoiceRepo} ./build/RHVoice
'';

But in the end, it didn't work because I assume that setup.py, after installation, tried to delete the RHVoice source, which it didn't have permission to do. So I copied the rhvoice-wrapper-data repository, added RHVoice as a submodule, removed the git requests in setup.py, and now everything works. It's not the most elegant solution, but it's the best I've come up with for now. Thanks everyone for your help.

Here is the working repository: https://github.com/wecmyrc/rhvoice-wrapper-data-patch

Here is an example of usage:

rhvoice-wrapper-data = super.rhvoice-wrapper-data.overridePythonAttrs (old: rec {
  src = pkgs.fetchFromGitHub {
    owner = "wecmyrc";
    repo = "rhvoice-wrapper-data-patch";
    rev = "752534d8a4a99fe69540df201ce2db244c5bf77a";
    sha256 = "sha256-wpci92SxMMEI05gxcqla0sN4aS8JCa0y43WCQwmD2fw=";
    fetchSubmodules = true;
    deepClone = true;
  };
  buildInputs = (old.buildInputs or [ ]) ++ [ super.setuptools-scm ];
});

I added an override I guess

In reply to @vengmark2:matrix.org
Did that work? If so, would you be OK to create a PR?
