I changed all the "let" to "var" and that is a workaround.

It's because you need a more recent version of NodeJS, for example I use NodeJS v7.2.0.

on Mac
rm -rf /usr/local/lib/node_modules

To install node version manager:
curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.32.1/install.sh | bash

To list versions:
nvm ls-remote

To install v7.2.1:
nvm install 7.2.1

cd path/to/alltomp3-cli-master
npm install -g

Thanks!
