Compilation error on file lib/ecto_enum.ex

[shakthimaan]

I am getting the following error when running mix ecto.create on a test project:

$ mix ecto.create
==> ecto_enum
Compiled lib/ecto_enum/postgres.ex

== Compilation error on file lib/ecto_enum.ex ==
** (CompileError) lib/ecto_enum.ex:124: type keyword() undefined
    (stdlib) lists.erl:1337: :lists.foreach/2
    (stdlib) erl_eval.erl:669: :erl_eval.do_apply/6

could not compile dependency :ecto_enum, "mix compile" failed. You can recompile this dependency with "mix deps.compile ecto_enum", update it with "mix deps.update ecto_enum" or clean it with "mix deps.clean ecto_enum"

Relevant file contents are shown below:

1. mix.exs

   defp deps do

   end

2. lib/my_app/ecto_enums.ex

   import EctoEnum
   defenum DegreeEnum, bachelors: 0, masters: 1 

3. web/models/user.ex

   defmodule MyApp.User do
   use MyApp.Web, :model
   
   schema "users" do
   ...
   field :degree, DegreeEnum
   ...
   timestamps()
   end

   Using ERL version on Ubuntu 15.04.

   $ erl --version
   Erlang/OTP 18 [erts-7.2] [source-e6dd627] [64-bit] [smp:2:2] [async-threads:10] [hipe] [kernel-poll:false]

   What could I be missing?

Was using an old version of Elixir (1.2.4). Compiles fine on 1.3.4.

@shakthimaan that's correct. EctoEnum 1.0 only works with Elixir 1.3.
