npm install fails with "node-gyp rebuild" error on node 8, 12, and 14

Trying to install the commit tagged 3.6.0, but it fails npm install with several node-gyp rebuild errors.

I've tried all the "xcode-select" troubleshooting on my mac, but no avail.

Seems to install on node 8.9.4, but not when I tried previously on 8.9.3. However, other troubleshooting steps were performed between then, so not sure what "fixed" it.

Haven't got it to run yet.

It runs.
