** (Mix) Could not start application hello_world_phoenix: HelloWorldPhoenix.start(:normal, []) returned an error: shutdown: failed to start child: HelloWorldPhoenix.Repo
    ** (EXIT) shutdown: failed to start child: Ecto.Adapters.Postgres
        ** (EXIT) an exception was raised:

Please verify you have added :postgrex as a dependency:

    {:postgrex, ">= 0.0.0"}

And remember to recompile Ecto afterwards by cleaning the current build:
