无法在MacOS Sierra 10.12.1上安装Jekyll

Question

I'm trying to install Jekyll using:

sudo gem install jekyll

but I get a error, I had found a solution on early mac version not for Sierra

this is the output:

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

current directory: /Library/Ruby/Gems/2.0.0/gems/ffi-1.9.17/ext/ffi_c
/System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/bin/ruby -r ./siteconf20170117-1518-aaehhb.rb extconf.rb
mkmf.rb can't find header files for ruby at /System/Library/Frameworks/Ruby.framework/Versions/2.0/usr/lib/ruby/include/ruby.h

extconf failed, exit code 1

Gem files will remain installed in /Library/Ruby/Gems/2.0.0/gems/ffi-1.9.17 for inspection.
Results logged to /Library/Ruby/Gems/2.0.0/extensions/universal-darwin-16/2.0.0/ffi-1.9.17/gem_make.out

thanks for advance!

You have to install the Ruby DevKit . Depending on your installation of Ruby, you have to select the correct way to install it.
