Hi Dr Bean, This is caused by an old version of target-lexicon being pulled in.
v0.13.3 of target-lexicon added support for Cygwin targets. https://github.com/bytecodealliance/target-lexicon/commit/03a3e6966c6ffa4d5685411a202339627fb28f41 It's a transitive dependency of pyo3-build-config. You would have to upgrade pydantic to v2.13.0b1 to fix that. They upgraded to PyO3 v0.28 in that release, which pulls in the fixed version of target-lexicon. https://github.com/pydantic/pydantic/commit/c42224acb31dd9f374124a74809332246e595194 https://github.com/PyO3/pyo3/commit/30a0209b212721674b619bfe405ae21e4a42a163 Best regards Oliver Old ________________________________ LÖWEN ENTERTAINMENT GmbH • Saarlandstraße 240 • 55411 Bingen am Rhein • Geschäftsführung: Christian Arras (Vorsitzender), Oliver Bagus, Dr. Daniel Henzgen • Vorsitz im Aufsichtsrat: Uwe Christiansen • Amtsgericht Mainz • HRB 23327 • USt.-IdNr.
