I have little knowledge of Ubuntu 14.04.
I need to install Node.js. The Ubuntu I am using is a big system for an organization so I don't have
sudo access, but I found that npm 1.3.10 is installed.
I am looking for a sequence of commands to install Node.js into my user directory. I have downloaded
Node.js from here on nodejs.org (LTS version, 64 bit) in
~/Downloads/node-v8.9.1-linux-x64.tar.xz. What do I do next?
