If you have any trouble installing erlang please consider joining the gitter support channel
Homebrew for Mac OS X
Update your Homebrew to latest:
$ brew update
Install Erlang and Rebar3:
$ brew install erlang rebar@3
On Linux
- Fedora 17+ and Fedora Rawhide:
sudo yum -y install erlang - Arch Linux:
sudo pacman -S erlang - Ubuntu/Debian:
sudo apt-get install erlang
It may happen that the packages above are dated. At least for ubuntu 16.04
it should still be able to run the tests. If your package gets to old (older
than OTP 17.0) please consider a build from source or using kerl
or asdf-vm and asdf-erlang
instead (follow installation instructions in the corresponding repositories).
Also fetch the latest rebar3 from rebar3.org and put it somewhere in
your $PATH and make it executable. (PRs that describe this better or
via package manager are welcome).
On Windows
Assuming choco is available (maybe you
already installed exercism CLI using it).
choco install erlang
choco install rebar3
Installing from Source
Get a recent Erlang OTP and follow their build-instructions.
