Getting undefined method 'unpack' for nil:NilClass on ruby 2.2

[myronmarston]

Ruby 2.2-preview2 was released a couple weeks ago and I decided to add it to RSpec's travis build matrix to make sure we're all green on it (and, if not, to provide feedback to the ruby core team about any regressions we find). However, I'm running into an exception from cucumber when travis runs our cukes on ruby-2.2-preview2. (Actually, after looking at the full build logs, it looks like it's using 2.2-preview1...I guess 2.2 in .travis.yml doesn't yet run preview2).

Here's an example of the failure:

https://travis-ci.org/rspec/rspec-expectations/jobs/43763060#L155

Here's the full stack trace:

This might be a regression in ruby rather than a bug in cucumber, but I'm not in a good position to figure that out so I figured I'd report it here and let the cucumber team work that out :).

@tooky can you take this one?

[tricknotes]

Probably this will fixed by cucumber/common@09d1b48 that introduced by #774

[coreyhaines]

Just brought down Ruby 2.2 and am getting this with cucumber version 1.3.17.

Any news on when an updated gem will be pushed for the 1.3.x path? I suppose I could update to to the 2.0 betas, if that is what will need to be done.

[davidbegin]

I was getting this error also with ruby 2.2 and cucumber 1.3.17, but using the v1.3.x-bugfix branch, solved it.

[mattwynne]

I just released 1.3.18 which has @tricknotes Ruby 2.2 support PR in it, so hopefully a quick bundle update cucumber should fix this for you all.

Happy Christmas!=

[myronmarston]

Thanks for the quick fix @mattwynne and @tricknotes!

Thank you guys! 👏

[davidbegin]

👍 Thank you!

[coreyhaines]

Great job!!! Thanks!

[kritiagg]

Is there a workaround to get it working in cucumber 1.3.15 as I have dependency on this version?

[aslakhellesoy]

@kritiagg have you tried running with 1.3.18 or 2.0.0?

[kritiagg]

I cant move to that version as one of the other gem is dependent on the version 1.3.15

[brasmusson]

@kritiagg Is the "one of the other gems" that is dependent on the version 1.3.15, the "Cucumber JSON Expanded formatter" (https://gist.github.com/blt04/9866357)? In that case you can upgrade to version 2.0 or 1.3.17-18, which include #700.

[kritiagg]

no, I am using gauntlt version 1.0.10
