uvloop fails to build with Python 3.13-rc1 #622
Description
- uvloop version: 0.20.0
- Python version: 3.13-rc1
- Platform: Linux (x86)
- Can you reproduce the bug with PYTHONASYNCIODEBUG in env?: N/A
- Does uvloop behave differently from vanilla asyncio? How?: N/A
I failed to install uvloop on Python 3.13-rc1 using this command docker run --name python --rm -i -t python:3.13-rc pip install uvloop. It ends up with those errors:

#587 will fix this
fafanoulele commented on Aug 28, 2024
Great! Thanks @fantix for the update!
triatic commented on Sep 18, 2024
I came across this using the Fedora 41 Beta, which ships with Python 3.13. Hopefully 0.21.0 will arrive on PyPI soon.
pythonmobile commented on Oct 5, 2024
waiting for this to be merged and live.
pythonmobile commented on Oct 9, 2024
can confirm that I could compile and install uvloop on 3.13.0 on ubuntu 22.04lts.
MarekSzadkowski commented on Oct 9, 2024
OK, I have this error too. Also on Ubuntu, but 24.04. Any clues?
rsommer commented on Oct 10, 2024
Current master builds fine against standard 3.13.0 but failes when python is build with free-threaded/nogil mode with several errors like this:
Tested against free-threaded python 3.13.0 installed via asdf using asdf install python 3.13.0t.
paullam328 commented on Oct 10, 2024
3.13.0 still have this bug yeah, especially when installing asyncio.
Solution: I dropped back to 3.12 for Docker img, and it worked.
Would be nice if the fix is installed for 3.13 though
theoturner commented on Oct 10, 2024
Same error on MacOS 15.0.1 with Python 3.13
MarekSzadkowski commented on Oct 11, 2024
I can admit 0.21.0b1 compiles successfully on Ubuntu 24.04 now. I went with my fork of CPython, installed all dependencies and it works.
However:
test_cython_coro_is_coroutine (test_cython.TestCythonIntegration.test_cython_coro_is_coroutine) ... python: Objects/codeobject.c:947: PyCode_Addr2Line: Assertion `addrq >= 0 && addrq < _PyCode_NBYTES(co)' failed.
Aborted (core dumped)
make: *** [Makefile:50: test] Error 134
I also tried to compile with forked Python (which is 3.14 pre-alpha, just 4 days old) and it failed.
jameshilliard commented on Oct 14, 2024
@fantix Think you could spin a new release with python 3.13 support?
fantix commented on Oct 14, 2024
Yup, on it. I'll promote the current beta into a release.
jakirkham commented on Oct 15, 2024
Think this can now be closed with 0.21.0 out
fantix commented on Oct 15, 2024
Yup, please feel free to reopen if 0.21.0 doesn't work.
Dev-Arhaan commented on Aug 29, 2025
Getting the same error on arch linux, python 3.13.7
