gem install jekyll ----error

Question

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

    /usr/bin/ruby 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 /usr/local/share/gems/gems/fast-stemmer-1.0.2 for inspection.
Results logged to /usr/local/lib64/gems/ruby/fast-stemmer-1.0.2/gem_make.out

怎么解？求助，。。。
