It's pre-installed in Kali, you should just need to run wpscan from the terminal. If you want to update it to the latest released version, update Kali's packages (apt-get update && apt-get upgrade).

@ethicalhack3r thanks for your reply, I am aware it is preinstalled in Kali because it is working fine on my other laptop. But when i ran WPScan on my Kali 2016.1 (Using virtualbox) it gave me this error [ERROR] cannot load such file -- nokogiri/nokogiri , unfortunately. So i am trying to get it to work and find a way to fix it.

@OutCell you need to run

apt-get install --reinstall wpscan

if you want to reinstall. Maybe you also need to reinstall all dependencies like nokogiri again to get it working, but it looks like your kali installation is currently broken.
