Can't add packages with python 3.11-dev

Issue

can't add packages with poetry using when the python version is specified by pyenv local 3.11-dev (the dev version is currently set to 3.11.4)
The steps are:

1. create a new directory and cd into the directory
2. pyenv local 3.11-dev
3. poetry init using default settings, changing Compatible Python versions from ^3.10 to ^3.11
4. poetry shell
5. poetry add numpy, returns with message:

Using version ^1.26.2 for numpy

Updating dependencies
Resolving dependencies... (0.1s)

Invalid PEP 440 version: '3.11.4+'

6. trying the same with another package: poetry add scipy, returns with message:

Using version ^1.11.3 for scipy

Updating dependencies
Resolving dependencies... (0.0s)

The current project's supported Python range (>=3.11,<4.0) is not compatible with some of the required packages Python requirement:
  - scipy requires Python <3.13,>=3.9, so it will not be satisfied for Python >=3.13,<4.0

Because no versions of scipy match >1.11.3,<2.0.0
 and scipy (1.11.3) requires Python <3.13,>=3.9, scipy is forbidden.
So, because toshiba depends on scipy (^1.11.3), version solving failed.

  • Check your dependencies Python requirement: The Python requirement can be specified via the `python` or `markers` properties

    For scipy, a possible solution would be to set the `python` property to ">=3.11,<3.13"

duplicate #6925

[hros]

thanks!!
that solved the issue with numpy (the python version no longer has a +, though it is a shame that I can't use the dev channel)
the other issue, item 6 installing scipy, still does not work

The message points to the docs, and suggests

For scipy, a possible solution would be to set the python property to ">=3.11,<3.13"

I couldn't get this to work. What is the proper way to get such packages to work
moreover, the initial message is unclear: "scipy requires Python <3.13,>=3.9, so it will not be satisfied for Python >=3.13,<4.0" since I'm using Python 3.11.4

please read the faq

[hros]

thanks!
the faq did not help
I was able to find a solution in a blog

I modified the pyproject.toml file:

[tool.poetry.dependencies]
python = ">=3.11,<3.12"

Initially, scipy asked for <3.13, another package I installed raised an error asking for stricter version bounds

please close
