Ruby

Install

:warning: Every time you update Ruby to a version in which the first two digits change, update your path to match.

1. For Mac - Install commandline tools and set SDKROOT

   xcode-select --install
   export SDKROOT=$(xcrun --show-sdk-path)
   

2. Install latest version of ruby with homebrew:

   brew install ruby
   

3. Update PATH

   echo 'export PATH="/usr/local/opt/ruby/bin:/usr/local/lib/ruby/gems/3.0.0/bin:$PATH"' >> ~/.zshrc
   

4. Check ruby and gem paths

   which ruby
   gem env
   

Gem

List installed gems

gem list

Remove all installed gems

for x in `gem list --no-versions`; do gem uninstall $x -a -x -I; done

Jekyll

1. 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"
   

2. Install Jekyll for Ruby

   gem install bundler jekyll
   

3. Install gems from Gemfile

   bundle install
