npm install fails due to node-gyp -v v3.8.0

[gitpusha]

Hi, I could not install the timenode CLI. I assume this must be due to an unresolved dependency or something to do with the new node v12.1.0?. Please help, I wanna run a timenode from CLI.
node v12.1.0
npm 6.9.0
npm i -g @ethereum-alarm-clock/cli
