npm run start fails on Debian 9

[ylacaute]

Hi, I cloned your project, install libs, run start and I have the error below.
OS : Debian 9
NPM : 5.3.0
NODE : v6.11.1

Any idea ?

$ npm run start

ultimate-hot-reloading-example@1.0.0 start /home/epi/prog/react/ultimate-hot-reloading-example
babel-node server.js

events.js:182
throw er; // Unhandled 'error' event
^
