One of your dependencies - memwatch-next - has not been updated to support Node 10. It appears that AirBnb is supporting a fork of this package at https://www.npmjs.com/package/node-memwatch.
Please see this related issue andywer/leakage#27.
Wouldn't mind't opening a PR for this but i'm not sure how you would like to addresses this. Switching packages is probably a safe bet.
