Elixir Compilation Error for Hello World program

when I want to write a simple hello world program with Elixir, it does not compile. I also cannot load it with 'c "hello.exs"'. It always gives me this error:

** (CompileError) hello.exs: internal error in expand_module;
crash reason: undef

  in function  erl_parse:new_anno/1
     called as erl_parse:new_anno({function,0,module_info,0,
           [{clause,0,[],[],
                    [{call,0,
                           {remote,0,{atom,0,erlang},{atom,0,get_module_info}},
                           [{atom,0,elixir_compiler_0}]}]}]})

    (stdlib) lists.erl:1336: :lists.foreach/2
    (elixir) lib/code.ex:307: Code.require_file/2

I use Linux Mint 17 and installed elixir with the script mentioned here:

Doing stuff in IEX does work however.

How do I get my compiler to work?

Thank you in advance!

Thanks for looking into this. I have now solved it this way: I had version 17.0 of Erlang. So I tried version 17.1 and it still didn't work. But after upgrading to Erlang 18.0 it miraculously worked.

Shoutout to kerl, which made the process quick and painless.

Linux distributions break Erlang into multiple packages, which is very confusing. You probably need to find an Erlang package called "erlang-parser" or "erlang-parser-tools" or similar and you should be good to go.
