Yes I'm running a fresh clone of your GitHub project. I'm on Linux Mint at the moment and I'm pretty much stumped by what is causing this.
I suppose I can try and reinstall node and nodejs and see what happens...
Yea, I've never experienced something like this. You can try to create a new file called `test.js` with the following content:
console.log('test')
Run it with `node test` and see if it logs test or not (if it doesn't your node is not working / outputting correctly).
