Error installing upgrade (Use of const in strict mode)

Below is what I receive when running the commands in an Administrator Command Prompt:

It's right there in the output, first line:

npm WARN engine npm-w> indow> s-upgrade@4.0.1: wa> nted: {"node":">= 4.0.0"> } (current: {"node":"0.12.2","npm":"2.7.4"})

Update Node and things will work!

Thanks! I'm new to Node. I thought NPM would update the Node.js version.
