Running mix deps.compile I get the following output:
==> eunit_formatters (compile)
Compiling src/eunit_progress.erl failed:
src/eunit_progress.erl:none: undefined parse transform 'eunit_striptests'
ERROR: compile failed while processing /var/www/myapp/releases/20150618041131/deps/eunit_formatters: rebar_abort
** (Mix) Could not compile dependency eunit_formatters, /root/.mix/rebar command failed. If you want to recompile this dependency, please run: mix deps.compile eunit_formatter
Running mix deps.compile eunit_formatter as it suggests results in the same error.
No clue what to do...
