Unable to install on Macs that use Apple M-series (ARM) chips

[wigging]

Installing the pvapy package on an Apple MacBook Pro (M series, ARM) fails in a conda environment as shown below:

Channels:
 - defaults
 - epics
Platform: osx-arm64
Collecting package metadata (repodata.json): done
Solving environment: failed
PackagesNotFoundError: The following packages are not available from current channels:
  - pvapy
Current channels:
  - https://repo.anaconda.com/pkgs/main/osx-arm64
  - https://repo.anaconda.com/pkgs/r/osx-arm64
  - https://conda.anaconda.org/epics/osx-arm64
To search for alternate channels that may provide the conda package you're
looking for, navigate to
    https://anaconda.org/
and use the search bar at the top of the page.

The same problem occurs when trying to install in a Python virtual environment using pip. It looks like the pvapy package is not installable on Macs that use the Apple M-series chips which are ARM processors.

I was able to install pvapy on a 2020 Apple M1 (Ventura 13.4.1) using pip.

I am unable to install pvapy on a 2023 Apple M2 (Sonoma 14.0) using either pip or conda. Not sure why it worked on the M1 but not the M2.

Sorry for the delay in response. I do not really have access to M2 machine for builds/packaging yet, but should get this in the next few weeks, at which point I'll try to generate package that you could use.

Could you please try "pip install pvapy" on your M2 machine, and let me know if it works?

I see this in my environment:

Just tried on an M2, looks like it worked!

Sounds good, thanks for letting me know. I'll close this issue, and if you see any problems with OSX/Arm64 package, let me know or open a new issue.
