Some ruby error?

[nazgul6]

Hi.

I'm getting the following error on two different computers (both macOS Mojave). Cant figure it out apart from thinking it must be Ruby related. Tried updating it to a newer version too, but that ends up with an error as well.

Here's the gsrd output:

/Library/Ruby/Gems/2.3.0/gems/gsrd-0.1.6/lib/gsrd.rb:46:in []': no implicit conversion of String into Integer (TypeError) from /Library/Ruby/Gems/2.3.0/gems/gsrd-0.1.6/lib/gsrd.rb:46:in block (2 levels) in go'

Any thoughts? Thanks.
