Install Ruby

It is possible you need to install ruby first.

If you are using Debian or Ubuntu Linux you can use apt. These instructions haven't been checked for recent versions of Ubuntu or Ruby. Please provide feedback.

For a Fedora-based system you can use yum or dnf to install the dependencies.

sudo dnf -y install ruby ruby-dev rubygems

Optional Dependencies

WhatWeb degrades gracefully when these dependencies aren't available.

MongoDB

Provides logging to Mongo databases.

sudo gem install bson
sudo gem install bson_ext
sudo gem install mongo

RChardet

Language character set detection. This is required for converting results to UTF-8, a dependency of logging to MongoDB. ⚠️ This feature slows performance ⌛

sudo gem install rchardet
