Could not compile dependecy :exometer_core

[Romario López]

I'm following the instructions in the readme and this happens

Elixir 1.3.2
Phoenix 1.2.1

** (Mix) Could not compile dependency :exometer_core, "/Users/romariolopezc/.mix/rebar3 bare compile --paths "/Users/romariolopezc/Repos/Phoenix/soranus/_build/dev/lib/*/ebin"" command failed. You can recompile this dependency with "mix deps.compile exometer_core", update it with "mix deps.update exometer_core" or clean it with "mix deps.clean exometer_core"

mix deps.compile exometer_core

You must make SURE you have lager 3.2.1 installed. Lager 3.2.0 isn't compatible with erlang 19 (which is what I'm assuming you're running), and the dependency of ~> 3.2.1 matches 3.2.0.

[Steve Cohen]

@RomarioLopez any luck?

[Romario López]

Sorry i haven't tried, this weekend going to try and post my results, thanks for the follow up! @scohen

[Jon Parise]

I'm going to close this because master is successfully building with lager >= 3.2.1 and OTP 19 and 20 these days.

[Max Kaplan]

Ran into this as well. Adding {:lager, ">= 3.2.1", override: true} as suggested above fixed it.
