  Dependency Error: Yikes! It looks like you don't have pygments or one of its dependencies installed. In order to use Jekyll as currently configured, you'll need to install this gem. The full error message from Ruby is: 'cannot load such file -- pygments' If you run into trouble, you can find helpful resources at http://jekyllrb.com/help/!

                    pygments

These are the message when I type jekyll serve.

Answer 1

If you use the command sudo gem install pygments.rb or gem install pygments.rb, it may not works

So you can try root:

su root
gem install pygments.rb

This fix my problem.

Answer 2

if you are a windows user, you could run CLI as administrator. This would help.

Answer 3

I had the same issue but fixed it installing pygments gem.

gem install pygments.rb

And adding it to my Gemfile.

gem 'pygments.rb'
