ArgumentError while running pronto run in Ruby 2.5.0

[giedriusr]

Hi,

My environment:

$ ruby -v
ruby 2.5.0p0 (2017-12-25 revision 61468) [x86_64-darwin17]
$ bundle | grep 'pronto'
Using pronto 0.9.5
Using pronto-rubocop 0.9.0
$ bundle | grep 'rubocop'
Using rubocop 0.52.1
Using guard-rubocop 1.3.0
Using pronto-rubocop 0.9.0

I am in my local branch, all changes has been committed and pushed to remote branch. When I try to run pronto, it gives me:

$ pronto run

With ruby 2.4.1 it works.

$ rvm use ruby-2.4.1
$ pronto run
  Unknown file type: rake, defaulting to ruby
app/models/model.rb:48 W: Similar code found in attribute.rb:48, product.rb:74 (mass = 60)

Not sure if it is only ruby related or is there anything else. Anyone else is having similar thing?

Update: in TravisCI I see that there is no Ruby 2.5 support. Any plans to support it?

I ran up against the same issue when I tried upgrading to Ruby 2.5 while using Pronto. It's fixed upstream here, but they haven't rolled a new release yet: https://github.com/libgit2/rugged/pull/730
