bootstrap script has syntax error

[msacks-dev]

Please excuse me if this is the wrong place to post this:

On CentOS 7 with epel-release version of erlang.

[root@localhost rebar3]# ./bootstrap ./bootstrap:129: syntax error before: '{' ./bootstrap:727: syntax error before: '{' escript: There were compilation errors.

What version of Erlang are you using? (it should be before 21, since that's when macro OTP_RELEASE was introduced.

Is it possible that you're using a version that doesn't understand map syntax?

Mind you that the latest rebar3 version offers support only for the current-2 previous Erlang/OTP versions (i.e. 23, 24, 25), as per the README: "The 3 newest major Erlang releases are supported at any given time"

Someone in the Erlang slack recently mentioned they were running CentOS 7 and the version of Erlang was a decade old. So I'm guessing that is indeed the issue.

If I'm looking at this right, according to your initial message, and @tsloughter's feedback, R16B03 is indeed ancient. At that moment in time I was still thinking about transitioning to rebar3 😄

Yeah the version for CentOS 7 is ~9 years old now and our window of support is on the last two major versions. You can either use a very old Rebar3 or a newer Erlang, but not a new Rebar3 and a very old Erlang.
