Error installing with Poetry on Python 3.12 under Homebrew on MacOS

[francispotter]

As others have pointed out, proper readline support seems to have disappeared from Python under Homebrew, and gnureadline provided an excellent alternative, which I used every day, until...

My projects that use Poetry can't build under Python 3.12.

• pip install gnureadline works under Python 3.12
• poetry install works under Python 3.11

Full experiment including error message

From pyproject.toml:

[tool.poetry.dependencies]
python = "^3.12"
gnureadline = "^8.1.2"

I admit to zero experience with C library development, but I posted the whole output from poetry install including the voluminous error messages.

This line looks important:

Note: This error originates from the build backend, and is likely not a problem with poetry but with gnureadline (8.1.2) not supporting PEP 517 builds. You can verify this by running 'pip wheel --use-pep517 "gnureadline (==8.1.2)"'.

I ran the pip wheel command suggested above and received an equally volumious 2nd error message.

Can you suggest a workaround?

Thank you!

Thanks for the report, Francis! The error messages look a lot like the ones Milos found in #62 on Python 3.11, but I have built successfully on 3.11 before, so it's still a bit of a mystery to me.

I recently became a "Poet" too :-), so I should be able to help out there. Thanks for the sandbox - I'll try that out and hopefully get back to you soon.

The override-readline-via-site-customization branch might also help, as that is my latest thinking.

I've finally released gnureadline 8.2.10 to PyPI. Thanks again for your patience 😅
