The script stops, and I can tell by `brew list` that nothing was installed – any ideas on where to go from here? Here's an attempt at reinstallation, overwriting all:

Seems to do the exact same thing, unfortunately. Thanks a ton for any help, I've been using your project for almost a year and I love it.
