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.

I have tried installing
liblzma-dev, didn't help. I also installed
2.0.3 that also didn't help.
