node & npm version

I'm sure it works on node v12 & npm v6 Install node and npm as follows.

sudo apt install nodejs npm -y

Install node version control tool "n" sudo npm install n -g

install node v12 & npm 6 sudo n 12

Delete old nodejs and npm sudo apt purge -y nodejs npm

Create symbolic link sudo ln -sf /usr/local/bin/node /usr/bin/node sudo ln -sf /usr/local/bin/npm /usr/bin/npm

Check your node & npm version node -v && npm -v
