ERROR: httpstan-4.13.0-cp311-cp311-macosx_15_0_arm64.whl is not a supported wheel on this platform.

My computer specs:

ProductName: macOS
ProductVersion: 15.3.2
BuildVersion: 24D81

$ python3 -c "import platform; print(platform.machine())"
arm64

Python 3.11.11

I was trying to install pystan using https://github.com/stan-dev/httpstan/releases/tag/4.13.0

but got this error:

$ python3 -m pip install dist/*.whl
ERROR: httpstan-4.13.0-cp311-cp311-macosx_15_0_arm64.whl is not a supported wheel on this platform.

My guess is the wheel file is not supported in macOS 15.3.2. Any help? thank you!

Have you tried to install httpstan from source?

Unless there is a specific functionality you need from PyStan, I would recommend moving to cmdstanpy, which is more up to date with Stan and has more developer support these days. It's also easier to install.

Yes, the error message is from installing from source.
