M1 Mac support? about node-rpio

[waltsatan]

How would you use this library on a Mac that doesn't have gpio pins?

[jperkin]

This library only supports Raspberry Pi and similar devices that expose GPIO interfaces. If there's something in the documentation that lead you to believe it might somehow be useful on Macs or other desktop computers then please let me know.

@jperkin Sorry for the late follow up here. I'm referring to running in mock mode.

From the documentation:

This module will only interface with hardware on Linux, but should compile on any other platform, where it will run in mock mode by default.

On an intel mac, mock mode works fine. On an m1, you receive the error.

In that case I'd check with whatever you are using for install of nodejs, seems like it's defaulting to building x86_64 objects which is wrong.

If I use the nodejs and npm packages from my pkgsrc repository (https://pkgsrc.joyent.com/install-on-osx/) it works fine:
