Installing LFE locally

Learn how to install LFE locally to solve Exercism's exercises on your own machine

First, make sure you have Erlang installed, following the instructions on the [Erlang][1] installation page as appropriate. [1]: /languages/erlang

Homebrew for Mac OS X

Update your Homebrew to latest:

$ brew update

Install LFE:

$ brew install lfe

Installing from Source

Install your system's "developer tools" or "essential build packages", git and Erlang's erl.

For example, on Ubuntu 18.04:

$ sudo apt-get install build-essential git erlang erlang-base-hipe

Afterwards you can download and build LFE with the following:

$ git clone https://github.com/lfe/lfe.git
$ cd lfe
$ make
$ make install

Once you have LFE compiled, you can start up the REPL (interactive session) by executing the lfe binary:

$ ./bin/lfe
