Answer 1

You need Node version 6.x or higher

take a look here: https://github.com/angular/angular-cli/issues/4604

Answer 2

As mentioned, you need Node version 6.x or higher.

Quick solution posted on Github by cdvillagra:

npm cache clean -f npm install -g n n stable 

(you might need to prefix those commands with sudo).

Also, on Ubuntu or similar you may want to remove your old version of node and then link the new one:

sudo ln -s /usr/local/bin/node /usr/bin/node
