Unable to start flamelex on console

[leonchen2012]

I followed the steps here:

git clone https://github.com/JediLuke/flamelex.git
cd flamelex
mix deps.get
iex -S mix run

And I got these errors:

I cloned these projects mentioned under JediLuke, run "mix deps.get" under each project, and then run "iex -S mix run", I got these error:

I could see the dependencies were messed up. Just want to try some elixir editor. Any other branch I can use?

Thanks
