npm install fails on serverless project on my mac, what is the cause?

Question

I'm attempting to go through a tutorial on serverless projects, yet have hit a point where I can't continue. I've installed the 'serverless' package and used it to setup the initial project structure using serverless install --url https://github.com/AnomalyInnovations/serverless-nodejs-starter --name notes-app-api

That appeared to succeed, the next step is to run 'npm install' however this is failing with the messages below. Any suggestions most welcome as to how to diagnose the cause.

npm install

> fsevents@1.1.3 install /Development/serverless/myproject/myproject-api/node_modules/fsevents
> node install

To answer my own question, the solution I found was to specify an updated version of the fsevents library. After adding "fsevents": "^1.2.4", to the devDependencies section in package.json, the project was able to build.
