I found this project today and tried to install on Node v12.16.1. Also lots of deprecation file not found warnings. At the end npm didn't even considered chimpy installed because of a failure installing fibers

npm ERR! code ELIFECYCLE
npm ERR! syscall spawn
npm ERR! file sh
npm ERR! errno ENOENT
npm ERR! fibers@3.1.1 install: `node build.js || nodejs build.js`
npm ERR! spawn ENOENT
npm ERR! 
npm ERR! Failed at the fibers@3.1.1 install script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

The "additional logging output above" is exactly what @vrudhay posted
