I get this following when I try to install nokigiri,

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

    current directory: /var/lib/gems/2.4.0/gems/nokogiri-1.9.1/ext/nokogiri
/usr/bin/ruby2.4 -r ./siteconf20181224-15718-15hfw3z.rb extconf.rb
mkmf.rb can't find header files for ruby at /usr/lib/ruby/include/ruby.h

extconf failed, exit code 1

Gem files will remain installed in /var/lib/gems/2.4.0/gems/nokogiri-1.9.1 for inspection.
Results logged to /var/lib/gems/2.4.0/extensions/x86_64-linux/2.4.0/nokogiri-1.9.1/gem_make.out

I have tried installing ruby-dev1, zlib1g-dev and liblzma-dev, didn't help. I also installed build-essential patch, ruby-dev version 2.0.0,2.0.2,2.0.3 that also didn't help.

    This looks like it expects a newer ruby version, have you tried installing ruby2.4-dev?
