The last supported version for node 4 is `1.143.6`
You can install it by doing `npm i -g firstname.lastname@example.org`
On 30th of April, 2018, Node.js 4 was officially marked as End of Life (EOL) and ceased to receive security updates.
We highly recommend that you follow a migration path to a stable and officially supported version of Node.js to be able to receive bug and security fixes. You’ll want to upgrade your version to at least Node.js 8+ Boron (although we recommend 10 Dubnium, the current LTS!)
