Erlang can be installed from source or from pre-built packages.
Instruction on how to install Erlang depends on the Operating System and are available on the Erlang OTP Download page. Another good source of information is available in the setup section of the Adopting Erlang web site.
The following section describes the various ways to install Erlang on macOS.
To install Erlang on your macOS system you can use one of the following ways:
- Using Homebrew, the simplest to get going, but also the least flexible way. A good first step for experimentation.
- Using Erlang Installer from Erlang Solutions. With Erlang Solutions'
ErlangInstallermacOS native application you can quickly install pre-built versions of Erlang for macOS and select which one you want to use. I provide extra information on how to extends this. - Using Kerl to build from source code using clones of the official Erlang git repositories.
- Using asdf-vm to build from source. asdf-vm extends Kerl and provides the ability to build lots of other tools, Elixir for instance. At the moment (and from what I currently know) this seems to be a very good choice because you can install Erlang but also Elixir and several other tools with it.
- Building from source using the Erlang/OTP instructions found in the Erlang/OTP Build and Install instructions. I have not yet gone through the entire process yet. Once I do I will provide more information.
You will probably want to use Erlang man pages when developing code. See the following sections:
- Manual installation of Erlang OTP Documentation and Man Files to get a local copy of Erlang HTML documentation and Erlang Man pages,
- Creating whatis files for Erlang man pages to understand the purpose of the whatis utility and its impact on the Erlang man pages, and
- Using Erlang Man files within Emacs to get the best of Erlang when using Emacs.
- Using Specialized OS Shells for Erlang, to use several versions of Erlang simultaneously.
- Using PEL with Specialized Shells for Erlang to Edit Erlang.
The next step is to setup files that are important when using Erlang. These files are described in the following sections.
Some extra information specific to macOS is available of my macOS Development Environment document.
If you are not familiar with Emacs and would like to learn about it, you may be interested by my Emacs customization and document project, PEL and the Erlang specific document Developing Erlang with PEL.
