[erlang-questions] How to install a specific version of erlang and uninstall a previously installed version on linux

[Abhishek Ranjan]

Hi,

I am a beginner in erlang and probably it is quite a naive question but I am new to both erlang and linux os as well. I an using Amazon AWS linux instance. I was installing ejabberd in the linux instance through source code when I came to know that I had to install erlang first so I ran command 

yum install erlang 

and the system installed erlang R14B ,then I found that it was needed that i install erlang/otp 17.1 for this.

So now I am a bit confused how to uninstall previous version of erlang first and then install a specific version of erlang i.e. Erlang/OTP 17.1 on Amazon AWS linux instance.

Thanks in advance.

Regards,

Abhishek
