Here is a short note of Jekyll installation based on the official documentation 1.

Installing the Latest Ruby

Ruby is preinstalled on macOS and it is not recommended to upgrade or uninstall libraries coming with the system. Here is the solution to safely install and use the latest Ruby without touching the macOS default Ruby.

Install package:

brew install ruby

Add to environment path:

echo 'export PATH="/usr/local/opt/ruby/bin:$PATH"' >> ~/.bash_profile

Open a new terminal window and verify:

$ which ruby
$ ruby -v
ruby 2.6.3p62 (2019-04-16 revision 67580) [x86_64-darwin18]

(Optional) For compilers to find ruby you may need to set:

export LDFLAGS="-L/usr/local/opt/ruby/lib"
export CPPFLAGS="-I/usr/local/opt/ruby/include"

(Optional) For pkg-config to find ruby you may need to set:

export PKG_CONFIG_PATH="/usr/local/opt/ruby/lib/pkgconfig"

Installing Jekyll

Install Jekyll using gem:

gem install --user-install bundler jekyll


$ gem list
