Error in poke.io.js?

[pokejones22]

Forgive me if this is a noob question, I have not used node.js much and mostly write in Objective-C and Swift.

I have created ichooseyou.js that simply contains:

var Pokeio = require('pokemon-go-node-api');

When I run it, I get the following error:

/Users/XXX/node_modules/pokemon-go-node-api/poke.io.js:21
const {RequestEnvelop, ResponseEnvelop} = pokemonProto;
      ^

SyntaxError: Unexpected token {

Any ideas?

@pokejones22 u will need a newer NodeJS version as it uses ES6 Features

[pokejones22]

So, if I do node --version
I get v5.10.1

But when I do brew upgrade node
Error: node 6.3.0 already installed

[pokejones22]

@gallexme do I somehow have two versions of node installed?

[pokejones22]

Never mind that, got it upgraded using nvm install node --reinstall-packages-from=node

Now when I run the ichooseyou.js script I get a new error:

module.js:568
  return process.dlopen(module, path._makeLong(filename));
                 ^

Error: Module version mismatch. Expected 48, got 47.
