[bug] Ratatouille.Window failed to start

[brendalf]

Hi folks,

@kessejones and I have been working on a personal project for a while.
Since yesterday, he can't run the project because of the error below.
On my computer, it's working fine.

We tried solving it with #11, but it didn't work.

** (EXIT from #PID<0.94.0>) shutdown: failed to start child: Ratatouille.Window
    ** (EXIT) an exception was raised:
        ** (MatchError) no match of right hand side value: {:error, -1}

Not sure if it helps, but I just encountered this error in my circleci build as well and in my case no terminal emulator environment variable was set. After setting $TERM, everything went smoothly.
