Controlling the python version without live prompts?

[tlc]

I've inherited a rye based Python project. I don't understand how to control the version of python. ry-install.sh is called unattended (with RYE_INSTALL_OPTION=--yes), so I can't answer the prompt Which version of Python should be used as default toolchain?

The .python-version file has 3.10.13. The pyproject.toml file has
requires-python = "== 3.10"

Today I noticed that the latest rye (0.21.0) installs python 3.12, which causes problems for us with a deprecated module.
Earlier ryes had been installing 3.11, but we hadn't noticed.

I couldn't figure out how to force a python version, so I forced an older rye with RYE_INSTALL, so we'd get 3.11.

How am I supposed to control the version of python?

Rye itself installs 3.12 for it's internal uses. For the project it should be picking up the version mentioned in the .python-version file. If that is not happening please paste the output of rye sync after wiping .venv.
