Failure to build MacOS 11.5

[kyselad]

Not sure if this is the same dependency bug listed in another issue, but npm fails to install node-g2core-api on my Mac. Errors seem to revolve around serialport. Any ideas whether this is an issue with the package or particular to my machine and/or how I'm installing? npm execute as superuser for what it's worth.

Just to update, I used the node n utility to downgrade the node version to 6.15.1, since an earlier issue mentioned serialport compatibility only through 6.x. After the node downgrade, installation of g2core-api using npm now works fine. So it seems this issue will remain until the serialport discrepancy is resolved. Perhaps best to merge with the earlier issue?
