Ruby: failed to require gherkin/parser

[kamaradclimber]

In general: version 3.2.0 of cucumber is incompatible with 6.0.10 of gherkin.

Summary

When using latest version of cucumber and gherkin gem, we get:

LoadError: cannot load such file -- gherkin/parser

Easy reproduction (with foodcritic command):

gem install --user foodcritic
foodcritic .

Full output:

LoadError: cannot load such file -- gherkin/parser

Thanks, @kamaradclimber. We are aware of this issue and are working on fixing it.

Until we make a new release, I suggest locking gherkin to ~> 5.1.

Duplicate of cucumber/cucumber-ruby-core#160 indeed.
I've followed https://rubygems.org/gems/gherkin to "Homepage" then https://github.com/cucumber/gherkin then https://github.com/cucumber/cucumber/tree/master/gherkin.
It seems that ruby code is hosted on another repository.

Thanks for your supper quick reaction

Hi @kamaradclimber, cucumber-core 3.2.1 has been released which pessimistically locks to v5.x. If you update using bundler, everything should now work as expected. 👍
