[SOLVED] Error "Failed to build gem native extension" while installing Jekyll

Issue

I am trying to install Jekyll on Fedora 26 using the command gem install jekyll --user-install

But I receive the following error:

Building native extensions. This could take a while...
ERROR:  Error installing jekyll:
ERROR: Failed to build gem native extension.

current directory: /my_user/.gem/ruby/2.4.0/gems/http_parser.rb-0.6.0/ext/ruby_http_parser
/usr/bin/ruby -r ./siteconf20180420-21754-1k1q01a.rb extconf.rb
mkmf.rb can't find header files for ruby at /usr/share/include/ruby.h

extconf failed, exit code 1

Gem files will remain installed in /my_user/.gem/ruby/2.4.0/gems/http_parser.rb-0.6.0 for inspection.
Results logged to /my_user/.gem/ruby/2.4.0/extensions/x86_64-linux/2.4.0/http_parser.rb-0.6.0/gem_make.out

I have Ruby installed:

ruby 2.4.3p205 (2017-12-14 revision 61247) [x86_64-linux]

And also I updated the Ruby Gems using gem update --system.

I searched the Stackoverflow, and I found a similar question solved for MacOS.

The output of gem env is as follows:

Solution

There have been a few other posts regarding problems with older versions of Fedora and jekyll, here's one: https://ask.fedoraproject.org/en/question/91815/problem-installing-jekyll-in-fedora-24/

Perhaps try:

sudo dnf install ruby-devel
gem install jekyll

or as per https://linuxsuperuser.com/install-jekyll-on-fedora-23/

sudo dnf install ruby-devel  
sudo dnf install redhat-rpm-config
sudo gem install jekyll
