support for osx-arm64

[phylyc]

Hi!

I have a mac with an M1 chip. Installing pyBigWig is no problem via pip, though anaconda is smart enough to only check the osx-arm64 channels and tells me that it's not available. Currently, there is no build for this chip.
Installing it via pip, when starting a python session and trying to import pyBigWig, I get the error

>>> import pyBigWig
Traceback (most recent call last): File "<stdin>", line 1, in <module> ImportError: dlopen([...]/env/lib/python3.10/site-packages/pyBigWig.cpython-310-darwin.so, 0x0002): tried: '[...]/env/lib/python3.10/site-packages/pyBigWig.cpython-310-darwin.so' (mach-o file, but is an incompatible architecture (have 'x86_64', need 'arm64e'))

Is there a plan to build for arm64? Or how can I build myself?
Thanks!

@phylyc It looks like you used a pip within an intel-python environment and then tried to run that using the arm-python. With the correct python in your path, you can prevent this with python -m pip install ...the normal pip stuff....

Thanks for the comment. I tried all possible things for a while, but it seems that the package in pip is indeed the intel version. The path to success was to download/clone the repo and use python -m pip install . in the repo within my miniconda environment. EDIT: Or simply python -m pip install git+https://github.com/deeptools/pyBigWig
