'npm install hashtable' fails on macOS Mojave v10.14.5

[luisw19]

Hi,

I just tired to install it on a macOS Mojave v10.14.5 and am getting a similar error to the ones described... I've tried several workarounds (including installing from fork https://github.com/fabrice102/node-hashtable.git as described in some articles I found in google) but none worked.

$npm install hashtable

> node-gyp configure build
