mach-nix: error: infinite recursion encountered, 'dateutil', 'python-dateutil'

I have ./default.nix

let
  mach-nix = import (builtins.fetchGit {
    url = "https://github.com/DavHau/mach-nix/";
    ref = "refs/tags/3.0.0";
  }) {};
in
mach-nix.buildPythonPackage {
  src = "https://github.com/twintproject/twint/archive/v2.1.4.tar.gz";
}

I build with nix-build and getting this error:

Hey, I just noticed that the wheel selection for macos is broken, therefore the resolver didn’t pick any wheel releases, falling back to sdist which sometimes can be troublesome. I fixed the issue and added some unit tests for it. This one should work now:

let
  mach-nix = import (builtins.fetchGit {
    url = "https://github.com/DavHau/mach-nix";
    ref = "refs/heads/master";
    rev = "3acbfc2ebd0b826cd046925493714a5e2f146d73";
  }) {};
in
mach-nix.buildPythonPackage {
 src = "https://github.com/twintproject/twint/tarball/ae5e7e1189be1c";
 overridesPre = [(
    pySelf: pySuper: {
      dateutil = null;
    }
 )];
}

In the meantime you can remove the duplicated dateutil from nixpkgs via an override:

let
  mach-nix = import (builtins.fetchGit {
    url = "https://github.com/DavHau/mach-nix";
    ref = "master";
    rev = "ffd51659df279b809d44c71855c57dbb58a105ea";
  }) {};
in
mach-nix.buildPythonPackage {
 src = "https://github.com/twintproject/twint/tarball/ae5e7e1189be1c";
 overridesPre = [(
    pySelf: pySuper: {
      dateutil = null;
    }
 )];
}
