Describe The Bug

When following the installation guide I get this error:

C:\Users\elias\Downloads\scraper filter\URS>poetry install
Installing dependencies from lock file

Package operations: 40 installs, 0 updates, 0 removals

• Installing numpy (1.24.3): Failed

ChefBuildError

Backend 'setuptools.build_meta:legacy' is not available.

Note: This error originates from the build backend, and is likely not a problem with poetry but with numpy (1.24.3) not supporting PEP 517 builds. You can verify this by running 'pip wheel --no-cache-dir --use-pep517 "numpy (==1.24.3)"'.

Expected Behavior

Actual Behavior

Error on installation

Steps To Reproduce

run:
git clone --depth=1 https://github.com/JosephLai241/URS.git
cd URS
poetry install
poetry shell
maturin develop --release

When running "poetry shell" it seems to kind of work:

C:\Users\elias\Downloads\scraper filter\URS>poetry shell
Spawning shell within C:\Users\elias\Downloads\scraper filter\URS.venv

(urs-py3.12) C:\Users\elias\Downloads\scraper filter\URS>

but when running "maturin develop --release" it does not find command "maturin"

Machine Specs

• Operating System: Windows 10
• Python Version: Python 3.9

I had to reinstall Poetry, delete the lock file to make it work.

The documentation says that URS works on Python 3.11+, but that is a lie. At least: the committed poetry.lock file does not work with Python 3.12. So indeed: just delete that file and try again. That's what fixed it for me.
