jiter build fails when running poetry install on Darwin

Running poetry install on Darwin with python

It has an optional dependency with that name, but that dependency uses the "dep:" syntax in the features table, so it does not have an implicit feature with that name.

Note: This error originates from the build backend, and is likely not a problem with poetry but with jiter (0.5.0) not supporting PEP 517 builds. You can verify this by running 'pip wheel --no-cache-dir --use-pep517 "jiter (==0.5.0)"'.

Downgraded to 3.12 fixed it for me.

you'd need to install rust and rust setup tools

simply running brew install rust should work
then you'd need to pip install setuptools_rust in the python3 venv

also, do roll back to 3.12 as you'd have issues when installing "greenlet"

and you might also need to set a env variable: PYO3_USE_ABI3_FORWARD_COMPATIBILITY=1 to bypass issues when installing "tiktoken"
