Cannot install hyperledger composer-cli on ubuntu because of g++ - hyperledger-composer

Question

On ubuntu 18.04 I get an eror when I try to install the hyperledger local development environment as supposed in
https://ibm-blockchain.github.io/develop/installing/development-tools.html.
It tells me that it doesn't know the g++ command.
My configuration listing:
npm: v6.9.0
docker: 18.x
docker-compose: 1.24
node: 10.15.3 (also tried with v11.10.0 and 8.9)
npm: 6.4.1
git: 2.17.1
Python 2.7.14
Following the error log after running "npm install -g composer-cli":
npm WARN deprecated core-js#2.3.0: core-js#<2.6.5 is no longer maintained. Please, upgrade to core-js#3 or at least to actual version of core-js#2.

Check your node & npm version. Below is the requirement:
Node: 8.9 or higher (note version 9 is not supported)
npm: v5.x
I have both and able to install it successfully on Ubuntu 18.
