erlang - Installing rabbitmq-server on RHEL

Question

When trying to install rabbitmq-server on RHEL:

[ec2-user@ip-172-31-34-1XX ~]$ sudo rpm -i rabbitmq-server-3.3.5-1.noarch.rpm 
  error: Failed dependencies:
     erlang >= R13B-03 is needed by rabbitmq-server-3.3.5-1.noarch

[ec2-user@ip-172-31-34-1XX ~]$ rpm -i rabbitmq-server-3.3.5-1.noarch.rpm 
  error: Failed dependencies:
    erlang >= R13B-03 is needed by rabbitmq-server-3.3.5-1.noarch

I'm unsure why trying to rpm install isn't recognizing my erlang install since running $ erlgives:

[ec2-user@ip-172-31-34-1XX ~]$ which erl
  /usr/local/bin/erl
[ec2-user@ip-172-31-34-1XX ~]$ sudo which erl
  /bin/erl

Answer 1

You need to install erlang via RPM for it to recognise the dependency.

The erlang RPMs are available in the EPEL repository:
