Ruby

Install the ruby package.

Add ruby gem path to shell rc, ie ~/.zshrc, or ~/.bashrc.

PATH="$(ruby -e 'print Gem.user_dir')/bin:${PATH}"

On Arch user gems will be installed to ~/.gem/ruby/ so they don't interact with anything installed by Pacman.

Bundler

Install bundler with.

gem install bundler

Bundler by default installs gems system-wide. To change this default add the following to your shell rc.

export GEM_HOME=$(ruby -e 'print Gem.user_dir')

Bundles can be installed explicitly at a certain location using:

bundle install --path .bundle

This would install a bundle in the working directory inside of a .bundle directory.
