on Ubuntu/Debian you would need to install:
sudo apt-get install libmagickwand-dev
on RedHat/Fedora/CentOS:
yum install ImageMagick-devel
To install rmagick with the gem system, you must have "imagemagick" on your system. The following error line says that rmagick failed to build because the native extension (imagemagick) does not exist on your system.
ERROR: Failed to build gem native extension.
On OSX, you can use brew (the best way in my opinion) to install imagemagick. Once brew is installed :
brew install imagemagick
gem install rmagick
On Mountain Lion (OSX), after:
brew install imagemagick
it may be necessary to force the re-creation of some symlinks manually before being able to install the rmagick gem.
> brew link -f jpeg
> brew link -f libpng
> brew link -f freetype
> brew link -f imagemagick
On fedora make sure you have ImageMagick-devel installed.

https://www.digitalocean.com/community/tutorials/how-to-install-ruby-and-set-up-a-local-programming-environment-on-ubuntu-16-04
Looks like it went well

sudo apt-get install ruby-dev
The above command fixed it for me.
Try installing libffi-dev

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

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

Any help would be appreciated.
First install the Command Line Tools in the latest Xcode-Version.
and then run sudo gem install rails
To install Command Line Tools, go to XCode Preferences > Downloads.
