I'm on a fresh Ubuntu installation and using the guide to install rails found here.
When I get to the final sudo gem install rails, I get this error:
Building native extensions. This could take a while...

Here is the code I put in and then the error followed: I am currently figuring out rails headers and see what could be happening. I follwed this article https://gorails.com/setup/ubuntu/16.04
and this article: http://ryanbigg.com/2014/10/ubuntu-ruby-ruby-install-chruby-and-you
and nothing.

Im also come up with this issue where I installed ruby environment manager rvm/ rbenv using sudo command.you can reinstall your ruby environment manager and avoid using sudo command or else all your gem installations would need sudo commands which you should avoid to prevent conflicts in the future.
My ruby version is ruby 2.3.1p112 (2016-04-26) [x86_64-linux-gnu]. And my gem version is 2.5.1

You are getting this error because there is no ruby development environment installed. Development environment is needed to compile ruby extensions,
You should install development first using command below:
$ sudo apt-get install ruby-dev
I had a similar issue and i solved it by installing ruby-dev:
sudo apt-get install ruby-dev

Not sure what to do at this point. Thanks!

You need the ruby dev headers files to compile gems.
You need the package ruby2.1-dev.
You may also need other packages like build-essential.
Try the following:
sudo apt-get install ruby2.1-dev build-essential
On earlier versions of Ubuntu such as 14.04, you will need the ruby2.0-dev package instead.
sudo apt-get install ruby2.0-dev build-essential
