How to install gulp?

I run npm install gulp in Ubuntu. Show this error:

My Server is Ubuntu 16.04.

Framework is Laravel 5.6.

ERROR: npm is known not to run on Node.js v4.2.6
Node.js 4 is supported but the specific version you're running has
a bug known to break npm. Please update to at least 4.7.0 to use this
version of npm. You can find the latest release of Node.js at https://nodejs.org/

How to issue this problem?

UPDATE 1

I run node -v show this message: v4.2.6

I run sudo apt-get install --only-upgrade nodejs show this message:
