jekyll serve error

Hi, Thanks for building such a nice template.
I have an issue running jekyll locally.
After clone, configure _config.yml and bundle install, just ran jekyll serve and got this error.

Before this error i had some other errors about jekyll plugins (?) which by running sudo gem install that_plugin solved.

Solved by this:
sudo gem install github-pages
