New command-line tools

It says:

Found /usr/local/lib/node_modules/espruino/cor­e/serial_nodeserial.js
No 'serialport' module found

So that means that the serialport NPM module (https://www.npmjs.com/package/serialport­) hasn't installed. Perhaps just try sudo npm install -g serialport first, and try and get that working (if it fails, which I guess it will, there should be a bunch of info online).

Maybe try: https://www.npmjs.com/package/serialport­#ubuntudebian-linux

Then once that's done, reinstall the CLI tools and hopefully they should drag in the serialport module this time and it'll all work great.
