I don't know ruby language, but it seems there's no error on elixir.rb formulae script.Firstly depends_on Erlang18Requirement causes this error even erlang installed.And it can go to make phase if I delete that depends_on ... line with brew install elixir but also spit an error /bin/sh: erl: command not found.It looks like...==> Downloading https://github.com/elixir-lang/elixir/archive/v1.4.5.tar.gz  Already downloaded: /home/algorist/.cache/Homebrew/elixir-1.4.5.tar.gz    ==> make  Last 15 lines from /home/algorist/.cache/Homebrew/Logs/elixir/01.make:  2017-07-04 16:57:44 +0900  make/bin/sh: erl: command not found  At least Erlang 18.0 is required to build Elixir  make: *** [Makefile:62: lib/elixir/src/elixir.app.src] Error 1But erl command runs fine on terminal with any shells and irb(ruby interactive shell?) I don't know why erl command doesn't work with linuxbrew.Please help!
linuxbrew can not find `erl`(Erlang) command when I try to install `Elixir` on openSUSE Tumbleweed
