I built my GitHub page with Jekyll. I have built one about 2 years ago, so this is second time try. There is a trace that I struggled to make Jekyll work right at the time. It took about one and half hour to set it up this time. I think I hopefully had some progress from the last time. I leave steps how to set it up here.


  • Ruby 2.3.0
  • rbenv with ruby-build
  • Bundler 1.11.2
  • GitHub account. Used user account page (username.github.io).


  1. Created a repo named keitaito.github.io (it’s important to use the username).
  2. Clone it to local.
  3. Create Gemfile, and write it like this:
    source "https://rubygems.org"
    gem "github-pages", group: :jekyll_plugins
  4. bundle install.
  5. (I think I did) bundle exec jekyll new .. It overwrote my Gemfile, so I fixed it. I forgot to remove ruby version and gem minima. These might not be needed.
    source "https://rubygems.org"
    gem "minima"
    gem "github-pages", group: :jekyll_plugins
  6. I (accidentally) have set my bundler up to install gems to vendor/bundle by default (global setting). So, all gems are put there. This led the following error when I did bundle exec jekyll serve:
    Invalid date '<%= Time.now.strftime('%Y-%m-%d %H:%M:%S %z') %>': Document 'vendor/cache/gems/jekyll-3.2.1/lib/site\_template/\_posts/0000-00-00-welcome-to-jekyll.markdown.erb' does not have a valid date in the YAML front matter.
  7. To fix the issue, I checked this one. I updated _config.yml file by adding a line exclude: [vendor].
  8. try again bundle exec jekyll serve, and it worked this time. A github page is built on localhost.
  9. I updated the .gitignore file. Since I put gems in vendor/bundle direcotry, I added it to the file. It’s like this:
  10. I have already committed vendor/bundle directory, so I fixed it with these commands. I can’t remember them for some reason, so I always need to google it:
    git rm -r --cached .
    git add .
    git commit -m "fixed untracked files"
  11. _config.yml is still default, so I updated it with my data.
  12. Commit all changes. and git push origin master. Voila! Not viola :)

I have no idea how to make code syntax highlighting and line breaks work right. It looks like default markdown and kramdown are a little different. Please let me know if you know how to do it. Also, is it possible to add comments in a post page, like DisQus?
