admin-lte/post_view.ex failing to compile

[thanos]

doing:

$ elixir -v
Erlang/OTP 21 [erts-10.2.3] [source] [64-bit] [smp:4:4] [ds:4:4:10] [async-threads:1] [hipe] [dtrace]
Elixir 1.8.1 (compiled with Erlang/OTP 21)

mix deps.get && cd assets && npm install && cd .. && mix ecto.setup && mix phx.server
$ mix ecto.setup

I get:
