i've delete the _build and the result is the same.
can you help me ?

You might be using too old of an Erlang version and rebar3 is using a guard expression that wasn't supported back then. What version are you trying to compile to?

[root@izuf66apgccn7tpnaw8k8lz ~]# erl
Erlang R16B03-1 (erts-5.10.4) [source] [64-bit] [async-threads:10] [hipe] [kernel-poll:false]

Eshell V5.10.4 (abort with ^G)

did this version support? it can't be update.it's newest version of my linux.

It has not been supported for over a year since it is now almost 6 years old (OTP-22 should be out in a couple of months at the most); there's one breaking release a year, and 3 minor releases a year as well. Release 3.5.2 is the last one to support R16: https://github.com/erlang/rebar3/releases/tag/3.5.2

You may fetch one of these older versions if you must.
