Installing Erlang

Gleam compiles to Erlang code, so Erlang needs to be installed to run Gleam code.

Precompiled builds for many popular operating systems can be downloaded from the Erlang solutions website,

Guides for installing Erlang on specific operating systems can be found below, as well as information on installing multiple versions of Erlang at once using version manager tools.
