Can't install raysect on mac

[khowarthCFS]

Hello,

I have found that I am unable to install raysect on my M3 Mac. As a minimum reproducible example, here is my pyproject.toml file contents:

[tool.poetry]
name = "test"
version = "0.1.0"
description = ""
authors = ["..."]
readme = "README.md"

[tool.poetry.dependencies]
python = "^3.11"
raysect = "0.7.1"

[build-system]
requires = ["poetry-core"]
build-backend = "poetry.core.masonry.api"

Running poetry install gives:

 % poetry install

Resolving dependencies... (0.2s)

Package operations: 1 install, 0 updates, 0 removals

  - Installing raysect (0.7.1): Failed

Note: This error originates from the build backend, and is likely not a problem with poetry but with raysect (0.7.1) not supporting PEP 517 builds. You can verify this by running 'pip wheel --no-cache-dir --use-pep517 "raysect (==0.7.1)"'.

I am on poetry version 1.8.2.

Running the command given in the error message (pip wheel --no-cache-dir --use-pep517 "raysect (==0.7.1)") also gives the same error.

I do have numpy installed:

% pip list numpy                                
Package Version
------- -------
numpy   1.26.2
pip     24.0

Even from within the poetry environment numpy is installed:

% poetry run pip list
Package                Version
---------------------- -----------
contourpy              1.2.1
cycler                 0.12.1
Cython                 3.0.10
fonttools              4.53.1
kiwisolver             1.4.5
matplotlib             3.9.1
numpy                  2.0.0
oldest-supported-numpy 2023.12.21
packaging              24.1
pillow                 10.4.0
pip                    24.0
pyparsing              3.1.2
python-dateutil        2.9.0.post0
six                    1.16.0

Appreciate any advice!

Hello, @khowarthCFS

Raysect 0.7.1 does not include pyproject.toml. The file was added later in version 0.8.1. So pip uses the legacy setup.py install method, but setup.py itself requires numpy and Cython pre-installed. I successfully installed Raysect 0.7.1. to an empty virtual environment (also on Mac) by preinstalling both NumPy 1.26 and Cython 0.29:

pip install "numpy<2"
pip install "cython<3"
pip install raysect==0.7.1
