Jekyll serve throws errors when serving default jekyll-bootstrap config

[Wsadowski]

When running jekyll serve in the directory cloned from the bootstrap repo, it throws a long list of errors:

Serving a site generated by "jekyll new" works flawlessly, however.

Hi Wsadowski
This morning set up an environment also encountered the same problem. I just wrote a note to share with you.

gem install jekyll                    #Default version jekyll 3.0.0     2015.11.1
gem uninstall jekyll                  #Uninstall high version jekyll
gem install jekyll -v '2.4.0'

problem goes to debug plugin. removing that one would resolve these errors

I've encountered this to using Jekyll v3.0.0. I resolved it by commenting out the first module in debug.ru

require 'pp'
# module Jekyll
#   # Need to overwrite the inspect method here because the original
#   # uses < > to encapsulate the psuedo post/page objects in which case
#   # the output is taken for HTML tags and hidden from view.
#   #
#   class Post
#     def inspect
#       "#Jekyll:Post @id=#{self.id.inspect}"
#     end
#   end

#   class Page
#     def inspect
#       "#Jekyll:Page @name=#{self.name.inspect}"
#     end
#   end

# end # Jekyll

module Jekyll
  module DebugFilter

    def debug(obj, stdout=false)
      puts obj.pretty_inspect if stdout
      "<pre>#{obj.class}\n#{obj.pretty_inspect}</pre>"
    end

  end # DebugFilter
end # Jekyll

Liquid::Template.register_filter(Jekyll::DebugFilter)
