Rye refuses installation of projects requiring a lower Python version

[Systemcluster]

Steps to Reproduce

In a project that requires a lower Python version than the system Python (or self-python), rye sync will fail with unsatisfiable requirements.

It seems to be using the default Python for this step even though it should be using the project Python.

❯ rye show
project: the-witcher-3-mod-manager
path: D:\Development\the-witcher-3-mod-manager
venv: D:\Development\the-witcher-3-mod-manager\.venv
target python: 3.10
venv python: [email protected]
virtual: false
configured sources:
  default (index: https://pypi.org/simple/)
❯ rye run python --version
Python 3.10.14

Reproducible with this project. It's an older project and that branch is experimental, it will fail to build, but it should still succeed to sync. these steps.

I don't have this issue with rye on a Linux system where self-python is 3.10, and pdm runs on the project without issues.

Extracted from #1291, please transfer this issue to the repo where it's most appropriate.

Expected Result

Done!

It seems cloning the linked repository to another location and running rye sync there works on the same system, but I cannot pinpoint why. I assume something must be different, even after deleting .venv, .python-version and the requirements files.

Is there other state stored somewhere that could influence this?

[charliermarsh]

My first guess was that you already had a .venv in the first folder, and that environment used Python 3.12.3. So Rye was trying to reuse that environment even though the Python version didn't match the requirement. But you mentioned that you removed .venv, and the behavior persisted, which would rule that out.

[Systemcluster]

Yeah, the .venv is definitely deleted. Here's the output with deleting it as the first step.

Looking at those logs it's obvious the issue is with ~\AppData\Local\uv\cache. It's picking the cached Python 3.12.3 immediately without considering the project restraints.

Workaround: Removing the cache directory makes rye sync work.

(Is there a subcommand for clearing the cache? I couldn't find one without spending too much time looking.)

I won't upload the cache directory here as it's over 2GB, but I can upload a subset if necessary.

[Systemcluster]

I found an easy way to reproduce this issue. The general configuration of my installation can be seen in the above comments where relevant.

Create a new directory, here I'll use rye-py-ver.

mkdir rye-py-ver

Create a pyproject.toml with a requires-python of >=3.12.

[project]
name = "rye-py-ver"
description = "Error repro for Rye"
version = "0.1"
requires-python = ">=3.12"

Now run rye sync to create the .venv.
Then delete the .venv and any other file that rye created so just the pyproject.toml is left again.

Next edit the pyproject.toml and set requires-python to >=3.10,<3.11.

[project]
#...
requires-python = ">=3.10,<3.11"

Now run rye sync again. It will fail with the error reported here.

@charliermarsh I think the issue should be easy to locate with this info.

Thanks, that's helpful! I'll give it a try when I have a free moment.

Ugh, bad news -- this actually didn't fail for me. On the second sync, I got:

Can you try it on Windows? I also can't reproduce it with Linux, but on Windows it reproduces every time. I can try on macOS later as well, but I assume the issue is Windows only.

[charliermarsh]

Ah ok. Yes I can try it on Windows but not today (don't have my Windows machine with me).

I am also experiencing the same issue as described in this issue.

OS: Windows11
platform: win-amd64

Even after changing the project version from >=3.12,<3.13 to >=3.11,<3.12 and completely removing and reinstalling the .venv, the current project is still recognized as version 3.12.4.

[charliermarsh]

I'll try to test it out today now that I'm back home.

[thanksshu]

I'm also experiencing this issue on the Windows platform, is there any follow up on this now?

+1. Similar issues faced on Windows. Tried pinning a lower version repeatedly and deleting and resyncing the venv. 'rye show' shows the version I pinned (3.11.9) but when I sync and install a dependency I get the same error as described above.

I ran into the same problem where I specified to use python 3.11.9 in the pyproject.toml and .python-version, but it kept using the 3.12.5 toolchain. Oddly, the issue was solved when I used requires-python = "~=3.11" in the pyproject.toml and specify the specific version (3.11.9) in the .python-version file.

[majidaldo]

works when i specify requires-python="<3.{one less (minor ver)}".
