Jenkins "Provide Node & npm bin/ folder to PATH" is empty

Question

I've installed Jenkins, added my repo, also installed NodeJS Plugin. But in Build Environment > Provide Node & npm bin/ folder to PATH I have empty dropdown.

(used https://strongloop.com/strongblog/roll-your-own-node-js-ci-server-with-jenkins-part-2/ tutorial) As result Jenkins crushes with

So, what's wrong?

You can specify a new Node installation under "Manage Jenkins" -> "Global Tool Configuration" -> "Add NodeJS".
