NodeJS install path on Linux Mint 17

I have installed Titanium on a Linux Mint 17 desktop. NodeJS is installed, version 0.10.25. NPM is installed, version 1.3.10. I have not installed the CLI, can't find a good tutorial for that.

When I startup Titanium, it asks for the NodeJS install path. I use locate nodejs to find the location, and get results like /usr/bin/nodejs and /usr/lib/nodejs/. I've tried to use /usr/bin/, /usr/bin/nodejs and /usr/lib/nodejs, but all fail.

How can I find the correct NodeJS path to be used in Titanium?
