Installing Jeykll failing?

[Dan Debrunner <dj...@debrunners.com>]

The website repo README.md says "requires jekyll".

https://github.com/apache/incubator-quarks-website/blob/master/README.md


I assume that means this: https://jekyllrb.com/

which indicates it uses gem to install, so gem is also required, which also requires Ruby.

However, I failed to get the gem install jekyll to work:

[root@streamsqse rubygems-2.6.2]# gem install jekyll

mkmf.rb can't find header files for ruby at /usr/lib/ruby/ruby.h 

extconf failed, exit code 1 



Does anyone have a write up of the process used to install Jekyll?

Thanks,
Dan.

Hi Dan,

Try this to get the header files:
$ yum install ruby-devel

Then try the jekyll install again. This may also be helpful:
