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' from /Library/Ruby/Gems/2.3.0/gems/gsrd-0.1.6/lib/gsrd.rb:44:in each' from /Library/Ruby/Gems/2.3.0/gems/gsrd-0.1.6/lib/gsrd.rb:44:in block in go' from /Library/Ruby/Gems/2.3.0/gems/gsrd-0.1.6/lib/gsrd.rb:40:in loop' from /Library/Ruby/Gems/2.3.0/gems/gsrd-0.1.6/lib/gsrd.rb:40:in go' from /Library/Ruby/Gems/2.3.0/gems/gsrd-0.1.6/lib/gsrd.rb:78:in <module:Gsrd>' from /Library/Ruby/Gems/2.3.0/gems/gsrd-0.1.6/lib/gsrd.rb:1:in <top (required)>' from /System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:127:in require' from /System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:127:in rescue in require' from /System/Library/Frameworks/Ruby.framework/Versions/2.3/usr/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:39:in require' from /Library/Ruby/Gems/2.3.0/gems/gsrd-0.1.6/bin/gsrd:4:in <top (required)>' from /usr/local/bin/gsrd:22:in load' from /usr/local/bin/gsrd:22:in

Any thoughts? Thanks.
