Symbol as array index (TypeError)

I’m unfortunate to be working on a Windows machine and my editor of
choice right now is NetBeans. I have a couple of projects that I’m
working on and everything has been fine until I started getting an
error. It literally went from working to not working without me
changing any code. I filed an issue for NetBeans but they say it’s a
Rails issue. I know it doesn’t have to do with my code because it
does it even when I create a blank output. When I try to start a
server, I get the following output:

I even tried a fresh install of NetBeans and a fresh project, but to
no avail. Can anyone steer me in the right direction? Thanks!
