Setting up your environment for Elixir support

The only prerequisite for Elixir is Erlang, version R16B or later. Official precompiled packages are available for most platforms.

To check your installed erlang version:

$ erl
Erlang R16B (erts-5.10.1) ...

OSX

Install via homebrew

$ brew update
$ brew install erlang
$ brew install elixir

Linux

Fedora 17+ and Fedora Rawhide

$ sudo yum -y install elixir

Arch Linux (on AUR)

$ yaourt -S elixir

openSUSE (and SLES 11 SP3+)

  • Add Erlang devel repo with zypper ar -f obs://devel:languages:erlang/ erlang
  • Install Elixir: $ zypper in elixir

Gentoo

$ emerge --ask dev-lang/elixir

Windows

Install Erlang (R16B02) from the official precompiled packages.

Direct Erlang installtion links

Install Elixir through Chocolatey

> cinst elixir

Test your setup

Elixir ships with three executables, iex, elixir, and elixirc. Fire up iex to run the Elixir shell. In iex, or "Iteractive Elixir," we can execute any valid Elixir expression and see the evaluated result.

Erlang R16B03 (erts-5.10.4) [source] [64-bit] [smp:4:4] [async-threads:10] [hipe] [kernel-poll:false] [dtrace]

Interactive Elixir (0.12.2) - press Ctrl+C to exit (type h() ENTER for help)
$ iex
iex(1)> IO.puts "Sweet Elixir!"
Sweet Elixir!
:ok
iex(2)>
