If you are trying to install Erlang on CentOS/7 you might be presented with the following errors:

The Erlang packages in the distro are not kept up to date, and go stale pretty quickly with the pace of Erlang development.

It’s better to use the packages from ESL: https://www.erlang-solutions.com/downloads/download-erlang-otp

Relevant Ansible tasks:

- name: install esl key
  rpm_key: state=present key=http://packages.erlang-solutions.com/rpm/
    erlang_solutions.asc
  become: true

- name: install esl repo
  copy: src=etc/yum.repos.d/erlang-solutions.repo dest=/etc/yum.repos.d/
    erlang-solutions.repo owner=root group=root mode=0644
  become: true

- name: install erlang
  yum: name=erlang state=latest update_cache=yes
  become: true
