Installing Elixir & the Phoenix framework with Homebrew on OS X

elixirphoenix.bash

brew update && brew doctor          # Repeat, until you've done *all* the Dr. has ordered!
brew install postgresql             # You'll need postgres to do this... you may also need to 'initdb' as well. Google it.

brew install elixir
mix local.hex                       
createuser -d postgres              # create the default 'postgres' user that Chris McCord seems to like -- I don't create mine w/a pw...

# Install the latest Phoenix. It will give us the command `mix phoenix.new`
mix archive.install https://github.com/phoenixframework/archives/raw/master/phoenix_new.ez

# Create the Phoenix project
mix phoenix.new <awesome_new_project>
# - or, excluding frontend stuff
mix phoenix.new <awesome_new_project> --no-brunch

# Follow directions after that; generally, you'll additionally need to enter:

cd <awesome_new_project>
mix ecto.create                     # create the db
mix phoenix.server                  # then visit: http://localhost:4000  -- then ctrl-C here *twice* to exit server

# voila!
