the solution is to run "npm install" inside the folder where are the scripts. It would be lovely to specify this in the installation instructions.
Anyway it doesn't work because it need to listen to udp 8008 and 8009, it seems is not listening (and my phone can't discover it), only tcp 8008 is opened (and works with browser)
