Please report to cython.
The yarl project doesn't import longintrepr.h directly.

[Hugo van Kemenade]

This has been reported to Cython in cython/cython#4461, fixed in cython/cython#4428 and released in 0.29.x: cython/cython@0f7bd0d

From the similar issue at aiohttp:

Are you asking for the release of a new version with C-files generated with newer Cython? If that's an action item right now, I think that it's doable.

I think this is the case 🤔

aio-libs/aiohttp#6600 (comment)

Can yarl do something similar?

[Thomas Wimmer]

@hugovk Maybe you can do it yourself. I had the same problem with pyzmq and found this helpful comment zeromq/pyzmq#1655 (comment)

[Hugo van Kemenade]

Thanks for the suggestion! This is for CI and I think we can wait until yarl installs smoothly for 3.11.

zeromq/pyzmq#1655 (comment) hasn't helped with yarl. As a workaround, I've used YARL_NO_EXTENSIONS=1 pip install yarl
