Install Jekyll & Bundler

Refer the documentation based on your Operating System.

Ubuntu MacOS Linux Windows

Instructions for MacOS

Install Command Line Tools

xcode-select --install

set SDKROOT (only macOS Catalina or later)Permalink

export SDKROOT=$(xcrun --show-sdk-path)

Install Ruby

Jekyll requires Ruby v2.5.0 or higher but MacOS Big Sur 11.x is already installed with Ruby 2.6.3. Check the version and confirm.

% ruby -v
ruby 3.0.2p107 (2021-07-07 revision 0db68f0233) [x86_64-darwin20]

If you’re running a previous version of macOS, you’ll have to install a newer version of Ruby.

Install Ruby using rbenv (Multiple Ruby versions)

This is very useful when you need to be able to run a given Ruby version on a project.

# Install Homebrew
/bin/bash -c "$(curl -fsSL"

# Install rbenv and ruby-build
brew install rbenv

# Set up rbenv integration with your shell
rbenv init

# Check your installation
curl -fsSL | bash

Re-Open the terminal and the version

## Install 3.0.0
$ rbenv install 3.0.0
$ rbenv global 3.0.0

$ ruby -v
ruby 3.0.0p0 (2020-12-25 revision 95aff21468)

## Install 2.7.0
$rbenv install 2.7.0

## set global version
$ rbenv global 2.7.0
$ ruby -v
ruby 3.0.0p0 (2020-12-25 revision 95aff21468)

## check versions
% rbenv versions     
* system (set by /Users/gini/.rbenv/version)

## set local version
% rbenv local 2.7.0

## show current local version
% rbenv version    
2.7.0 (set by /Users/gini/codes/
gini@greenmango % 

Install Jekyll

(Use localinstall rathr than Global Install)

gem install --user-install bundler jekyll
## --[no-]user-install          Install in user's home directory instead

Append your path file with the following, replacing the X.X with the first two digits of your Ruby version:

# If you're using Zsh
echo 'export PATH="$HOME/.gem/ruby/X.X.0/bin:$PATH"' >> ~/.zshrc

# If you're using Bash
echo 'export PATH="$HOME/.gem/ruby/X.X.0/bin:$PATH"' >> ~/.bash_profile

# Unsure which shell you are using? Type
echo $SHELL

Check that GEM PATHS: points to your home directory:

gem env

Instructions for Ubuntu

Install packages

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

## RHEL8/CentOS8
sudo dnf install ruby ruby-devel
sudo dnf group install "Development Tools"

Configure gem 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

Install jekyll & bundler

gem install --user-install bundler jekyll

Test your site

Goto your project directory

bundle exec jekyll serve

Benchmarking your Jekyll website

$ bundle exec jekyll build --profile

Updating the GitHub Pages gem

If the github-pages gem on your computer is out of date with the github-pages gem on the GitHub Pages server, your site may look different when built locally than when published on GitHub. To avoid this, regularly update the github-pages gem on your computer.

  • If you installed Bundler, run bundle update github-pages.
  • If you don’t have Bundler installed, run gem update github-pages.

If no Gemfile

bundle init
bundle add jekyll
bundle install --path vendor/bundle

Jekyll-Admin - GUI Editor

Add Plugin in Gemfile

group :jekyll_plugins do
    gem 'jekyll-admin'

Add configuration in _config.yaml

  homepage: "posts"
    #- posts
    #- pages
    #- staticfiles
    - datafiles
    #- configuration

Refer Jekyll Admin - Documentation and GitHub for details.
