"node-gyp rebuild" error in mac - node.js

Question

I wanted to follow this page to run JSBin locally.
I just installed xcode 8.2 in my mac. Now, npm -v returns 3.10.9; node -v returns v7.2.1. However, npm install raised errors:
/Users/softtimur/Startup/WebProjects/jsbin$ npm install

Does anyone know what's wrong here?

Answer 1

Downgrade Node to v10, like this:
brew uninstall node
brew install node#10
brew link --force --overwrite node#10
npm i should finish without errors now.

Answer 2

The problem is that hashring v3.0.0 depends on an older version of nan (v1.3.x), which is not compatible with recent versions of node. It should be noted that as of this writing, the current version of hashring (v3.2.0) no longer contains an addon, it's javascript only.
The hashring dependency comes from jsbin's memcached dependency, which is currently hard coded to a specific git commit hash. There was a PR to update this dependency a number of months ago but was apparently dismissed because the maintainer(s) are apparently not interested in supporting modern versions of node. You may want to create an issue on their tracker to voice your concern about node compatibility.
