- Set up Jekyll
- Use
bundle exec jekyll serve --watchto locally build and preview your Jekyll site - Use
bundle updateto update the Ruby github-pages and jekyll gems
Use rm -rf .bundle/ vendor/ ; git clean -fX to solve this problem if it occurs locally:
Your Gemfile.lock is corrupt. The following gem is missing from the DEPENDENCIES section: 'mini_portile2'
and if it occurs on Tracis CI then add install: bundle install to .travis.yml
and git rm Gemfile.lock && echo "Gemfile.lock" >>.gitignore;
needed because its default is bundle install --jobs=3 --retry=3 --deployment,
the --deployment if a Gemfile.lock exists,
see https://docs.travis-ci.com/user/languages/ruby/#Travis-CI-uses-Bundler,
and that is causing some issues, see rubygems/bundler#4467.
Use sudo dnf install ruby-devel to solve this problem:
bundle install

Use jekyll 3.3.0 instead of jekyll _3.3.0_ (as shown on help.github.com) to solve this problem:
jekyll _3.3.0_ new .

Add gem 'therubyracer' to the Gemfile and redo bundle install
(or one-time do gem install therubyracer, but in Gemfile is better to share with others),
