Fail to get edts working properly

[mping]

Hi, I'm using emacs:

GNU Emacs 24.5.1 (x86_64-apple-darwin13.4.0, NS apple-appkit-1265.21)
 of 2015-04-10 on builder10-9.porkrind.org

I tried installing edts from elpa, it wouldn't start. These are the steps that I took to fix the compilation error:

• edit lib/webmachine/rebar.config, remove the line {erl_opts, [warnings_as_errors]}.
• edit lib/edts/rebar.config, put lager_transform in front {lager_transform, parse_transform}
• call make on edts root folder

But it is still not working, the edts buffer complains:

Protocol 'inet_tcp': invalid node name: edts-20160812.729@Miguels-MacBook-Pro
;; I tried with a different host name
Protocol 'inet_tcp': invalid node name: [email protected]

Starting emacs in another directory shows a different error:

;; messages buffer
Package iswitchb is obsolete!
File mode specification error: (error "EDTS: Could not start main server")
EDTS [error]: Unexpected reply: nil [2 times]

;; edts buffer

Please advise.

I compile edts use erlang 18, and change to 19 when I use emacs.
