Going from Zero to Rails on OS X

README.md

1. Open a Terminal window

2. Install Xcode command line tools:

   xcode-select --install
   

   (Follow pop-up prompts to install command-line tools)

3. Install the homebrew package manager:

   /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
   

   You may be prompted for your admin password. It's fine. The installer needs to set the right permissions on /usr/local.

4. Install the asdf version manager:

   brew install asdf
   

5. Configure your shell to load asdf:

   echo 'export ASDF_DIR=$(brew --prefix asdf)' >> ~/.bash_profile
   echo '. $ASDF_DIR/asdf.sh' >> ~/.bash_profile
   

6. Close your Terminal window and open a new one.

7. Install ruby:

   asdf plugin-add ruby
   asdf install ruby 2.5.5
   asdf global ruby 2.5.5
   asdf reshim ruby
