Python Version Conflict

[marcelkahlen]

Dear all,

for my pyproject.toml, I restrict the python version with python = "^3.10". This works for me for many of my python packages with mutliple additional dependencies.

However, when I add pyinstaller as a dependency, I get the following conflict on calling poetry install:

The current project's supported Python range (>=3.10,<4.0) is not compatible with some of the required packages Python requirement:
  - pyinstaller requires Python <3.13,>=3.8, so it will not be satisfied for Python >=3.13,<4.0

Because metrology-analyzer depends on pyinstaller (6.5.0) which requires Python <3.13,>=3.8, version solving failed.

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

    For pyinstaller, a possible solution would be to set the `python` property to ">=3.10,<3.13"

When I restrict restrict the python version to python = ">=3.10,<3.13" then it works.

I do not understand why poetry is unable to solve the version problem with python = "^3.10" since this should also allow python versions >=3.10,<3.13 which are suitable for pyinstaller.

I use python 3.11.2 and poetry 1.8.2.

Thanks a lot for your help!
Marcel

as the error message says

pyinstaller requires Python <3.13,>=3.8, so it will not be satisfied for Python >=3.13,<4.0

also please read the faq

I still do not see why poetry is not allowing the installation since my python version 3.11 satisfies the python restriction and the pyinstaller restriction.

Unlike pip, Poetry doesn’t resolve for just the Python in the current environment. Instead it makes sure that a dependency is resolvable within the given Python version range in pyproject.toml.

I see. Thank you both!
