Can't install appmetrics with npm - npm

Question

I'm trying to install access-watch with no success.
After cloning the repo I call npm i and I get the following error. It appears to occur when the installation process tries to install appmetrics. So I tried npm i appmetrics and got the exact same error, hence the title of this question.
Here's the tail of the trace,
$ cd access-watch
$ npm i

I know node-gyp must be installed and it is:
$ node-gyp --version
v8.2.0
I found an issue in appmetric's github and ran with CC=gcc-9 but to no success.
Thanks!
