Jekyll on Ubuntu

Install dependencies

Install Ruby and other prerequisites:

sudo apt-get install ruby-full build-essential zlib1g-dev

Avoid installing RubyGems packages (called gems) as the root user. Instead, set up a gem installation directory for your user account. The following commands will add environment variables to your ~/.bashrc file to configure the gem installation path:

echo '# Install Ruby Gems to ~/gems' >> ~/.bashrc
echo 'export GEM_HOME="$HOME/gems"' >> ~/.bashrc
echo 'export PATH="$HOME/gems/bin:$PATH"' >> ~/.bashrc
source ~/.bashrc

Finally, install Jekyll and Bundler:

gem install jekyll bundler

That’s it! You’re ready to start using Jekyll.
