textual-web can't be installed while depending on Python 3.12 (macOS)

[davep]

It appears that textual-web can't currently be installed when Python 3.12 will be the environment's Python (at least on macOS, Python installed via pyenv).

Using pipx, for example, I get the following error:

Fatal error from pip prevented installation. Full pip output in file:
    /Users/davep/.local/pipx/logs/cmd_2023-11-06_08.18.46_pip_errors.log

pip failed to build packages:
    aiohttp
    uvloop

Some possibly relevant errors from pip install:
    fatal error: too many errors emitted, stopping now [-ferror-limit=]

Error installing textual-web.

An example log:

cmd_2023-11-06_08.12.43_pip_errors.log

If I force Python 3.11:

$ pyenv global 3.11
$ pipx install --force --python (which python) textual-web

(using fish above, use appropriate substitution syntax for your shell of choice) it installs just fine.

It looks like Python 3.12 is only supported in the aiohttp beta currently.

It looks like Python 3.12 is only supported in the aiohttp beta currently.

aiohttp v3.9 has just been released. It looks like uvloop added Python 3.12 support in v0.18.

Also running into this issue, but only for uvloop

Same issue for Windows 10 on python 3.12. Some package used by textual-web depends on multidict and frozenlist (maybe also aiohttp?), which both don't have wheels for Windows yet.
PRs for both of them exist already though:
aio-libs/frozenlist#553
aio-libs/multidict#877

3.12.1 on Ubuntu 23.10, pipx fails with:

pip failed to build package:
    uvloop

But, in a 3.12.1 virtualenv?

$ pip install uvloop

Go figure.

Same issue here. Unuseable on Fedora 41 in a venv. Seems like this project is dead now.
