What version of
types-typed-astdo you have installed in your environment?AlexWaygood commentedon Nov 8, 2022
If you have
types-typed-ast<1.5.8installed locally, you'll need to runpip install -r test-requirements.txtagain locally. It's now pinned to>=1.5.8in CI:mypy/build-requirements.txt

Thanks @AlexWaygood
This is in the context of updating the
mypypackage for Debian, so we gettypes-typed-astfrom a package we callpython3-typeshedwhich is built from a 2022-06-10 snapshot of https://github.com/python/typeshed/tree/ad48606a0d901d907f2428917d7a5f97959b4733I'll see about updating the
python3-typeshedpackage in Debian to something newerAlexWaygood commentedon Nov 8, 2022
In order for mypy selftest to pass, it'll need to be a copy of typeshed with python/typeshed@c72c9a6 (a commit on August 29) included 🙂
