need complete dependency for demo.

[minghu6]

It needs elixir and hex installed.

[benoitc]

what’s the purpose of this ticket?

[minghu6]

README of examples/demo just said:

Build

$ rebar3 compile
$ rebar3 shell
Erlang/OTP 18 [erts-7.3] [source] [64-bit] [smp:8:8] [async-threads:0] [hipe] [kernel-poll:false] [dtrace]

Eshell V7.3  (abort with ^G)
1> 'Elixir.MacroApp':run(). 

etc.

However, rebar3 compile on the demo also need elixir and hex plugin for mix installed,
So it's better to Add somethings on README like

Dependency

elixir (if no version limit)
hex for mix

[benoitc]

Aahh I understand now :) Yes indeed. I will edit the readme asap. Thanks!
