What’s your Gemfile look like?

Have you tried running bundle update?

my Gemfile is

source 'http://rubygems.org'

gem 'github-pages'
gem 'rouge'
gem 'jekyll'
gem 'jekyll-mentions'
gem 'jekyll-feed'
gem 'jekyll-sitemap'
gem 'jekyll-gist'

and bundle update

Bundle updated!

Maybe try gem uninstall colorator and remove any and all versions of it. Then install everything again.

bundle install
bundle exec jekyll build

Seems like something is up with colorator according to the error above. I’m not familiar with that gem or what it’s used for.

Thanks it work. my issue is solve
