macOS Prerequisites
- Homebrew
asdferlangelixir
Install Homebrew
Homebrew bills itself as the missing package manager for macOS.
Follow the instructions on https://brew.sh to install:
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
Install asdf
asdf is an extendable version manager with support for Ruby, Node.js, Elixir, Erlang & more: https://asdf-vm.com
Install it using Homebrew
brew install asdf
Install Erlang
Using asdf, first install Erlang. As of this writing, the latest stable version is 22.3.3:
asdf plugin add erlang
asdf install erlang 22.3.3
(The last command above can take a while to finish, and will need to download about 53.2MB of data.)
Afterwards, set the global erlang version:
asdf global erlang 22.3.3
Verify Erlang installation:
$ erl -s halt
Erlang/OTP 22 [erts-10.7.1] [source] [64-bit] [smp:12:12] [ds:12:12:10] [async-threads:1] [hipe]
Install Elixir
Again using asdf, now install Elixir. As of this writing, the latest stable version is 1.10.3:
asdf plugin add elixir
asdf install elixir 1.10.3
asdf global elixir 1.10.3
Verify Elixir installation:
$ elixir --version
Erlang/OTP 22 [erts-10.7.1] [source] [64-bit] [smp:12:12] [ds:12:12:10] [async-threads:1] [hipe]
Elixir 1.10.3 (compiled with Erlang/OTP 21)
You may now proceed to the Basics.
