Where has JSBin been installed? - 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. npm install returns
/Users/softtimur/Startup/WebProjects/jsbin$ npm install
> jsbin#3.40.2 postinstall /Users/softtimur/Startup/WebProjects/jsbin
> grunt build && npm run selenium:install

Done, without errors.

It seems that jsbin has been installed, however, I could not find it under /usr/local/lib/node_modules/npm/node_modules/.
Does anyone know where it is?
Edit 1: npm start returns:
/Users/softtimur/Startup/WebProjects/jsbin$ npm start
> jsbin#3.40.2 start /Users/softtimur/Startup/WebProjects/jsbin
> (sleep 2 && open http://localhost:3000) & ./bin/jsbin

Additionally, I think .bin/jsbin it runs is what has been inside the git folder; it was not built by my npm install.

Answer 1

I could not find it under /usr/local/lib/node_modules/npm/node_modules/
That is to be expected, because you copied the package repo to ~/Startup/WebProjects/jsbin, for use in development, as opposed to using npm install -g jsbin to install it globally, for regular use.
Using npm start from ~/Startup/WebProjects/jsbin, as Benjamin suggests, is the right approach.
npm start does find the jsbin executable, namely in subfolder ./bin (if you look in package.json, key "scripts", you'll see line
"start": "(sleep 2 && open http://localhost:3000) & ./bin/jsbin").
The error message you're getting is actually generated by jsbin itself, indicating a problem with the package's installation.
