When attempting to install jekyll appears an error

I'm having some trouble installing jekyll. Can't quite figure out how to patch the missing link.

Heres the full post:

root@cherob:~# gem install jekyll
Building native extensions.  This could take a while...
ERROR:  Error installing jekyll:
ERROR: Failed to build gem native extension.

I had the same error while installing. You will have to install des Ruby dev packacke:

sudo apt-get install ruby2.4-dev

This will install the developement package for 2.4. You should install 2.1 as you are using this version. I had the problem, that the package could not be found in the repositories. So I used the following PPA:

$ sudo apt-add-repository ppa:brightbox/ruby-ng
$ sudo apt-get update

https://launchpad.net/~brightbox/+archive/ubuntu/ruby-ng

Version 2.1 is also available in this repository.

Such error usually means that you don't have build tools installed. As far as I understood you are using linux, so you can run something like

apt-get install build-essential

This command is for deb-bases distros. So you can use something similar if you use a different distro.
