Difficulty using Maturin on MacOS

[jblindsay]

Hello, I have developed a PyO3 project which I have been using Maturin to build Wheels for. On Linux, >>maturin develop --release works with no issue. However, using the same set-up (I followed the tutorial in the user guide and am in a venv environment) I get the following error on an ARM mac:

Finished release [optimized] target(s) in 44.42s
📦 Built wheel for abi3 Python ≥ 3.7 to /var/folders/4p/gqqkw1lx7p57mzn2z_tbr99h0000gn/T/.tmpZ6JHLf/whitebox_enterprise-0.1.0-cp37-abi3-macosx_11_0_arm64.whl
💥 maturin failed

--- Stdout:

--- Stderr:
ERROR: whitebox_enterprise-0.1.0-cp37-abi3-macosx_11_0_arm64.whl is not a supported wheel on this platform.

I've also tried to compile on an Intel Mac as well and received the same error. Is Maturin not supported on Macs? Something tells me this isn't the case.

What maturin version are you using? What Python version and architecture are you using?

Sounds like your development environment is messed up. Please try the solution in #979 or #982.

Silly me, I see that the python script you had me run earlier indicated x86. Okay, so I assume that that was the version installed in my virtual environment when I ran python3 -m venv .venv, as per the Maturin tutorial. So the question for me now is, how do I force it to use the ARM based version? Or alternatively, how do I upgrade Maturin to v0.13 instead?

I really do apologize for all this bother. I tried your solution for updating:
(.venv) johnlindsay@Johns-MacBook-Pro-2 whitebox_enterprise % pip install -U maturin Requirement already satisfied: maturin in ./.venv/lib/python3.9/site-packages (0.13.0) Requirement already satisfied: tomli>=1.1.0 in ./.venv/lib/python3.9/site-packages (from maturin) (2.0.1) (.venv) johnlindsay@Johns-MacBook-Pro-2 whitebox_enterprise % maturin --version maturin 0.12.19

So it seems the upgrade did not take.

It's not easy to explain because I don't know how did you install your current Python interpreter. I assume that you install it before there were official arm64 Python releases. Anyway you should try pyenv.

You can also get maturin 0.13 from Homebrew: brew install maturin if pip install -U maturin doesn't work for you.

Looks like something wrong with PATH, try uninstall maturin (pip uninstall maturin) then reinstall it to get a clean environment.

Okay, I'll try that. Thanks again for all your help.
