The Definition and the Completion don't work on Ruby 2.2

[steiley]

I encountered the following error when trying to start the Definition or the Completion using the language server on Ruby 2.2.

NoMethodError: undefined method `fetch_values' for {:line=>80, :character=>33}:Hash

Actually there is no function called fetcth_values ​​in the Hash class of Ruby ​​2.2.
But I think It is not necessary to implement fetch_values for Ruby ​​2.2.
How about removing Ruby ​​2.2 from support?

Wow, sorry the coverage isn't enough 🙇
I'd like to support Ruby 2.2 until EOL. (It will be this December though)
So I'll add test and fix this problem.

[steiley]

I see.
I understand that.

[mathieujobin]

does that means this never worked?

@mathieujobin
Sorry, I haven't fixed this problem before Ruby 2.2 EOL.
Are you still using 2.2?
