Wrong dependencies management makes the gem require activesupport 5.0 thus Ruby 2.2.2 about numbers_and_words

[eLod]

@dblock i believe he meant @Koroeskohr 's gemfile, the same you suggested. I think we all agree, that @Koroeskohr 's problem is that he wants to use numbers_and_words, but by default that fetches AS 5.0 for him, which requires ruby 2.2, while he wants 2.1. the solution as both of you said is just pin AS in his gemfile.

edit: actually it has another layer. so @Koroeskohr is developing a gem. and such i guess he wants his gem to work on both ruby 2.1 and 2.2. that said i was under the impression bundler/gemspec is smart enough to understand that on 2.1 it can only install AS < 5.0.

@Koroeskohr can you provide us more information what is failing/how to reproduce?

the gem now requires ActiveSupport 5.0

I don't think so: https://github.com/kslazarev/numbers_and_words/blob/master/Gemfile#L4. It should use any version of activesupport.

Do you mind posting a sample Gemfile that reproduces the issue?

[Koroeskohr]

My gem just has those two dependencies in the .gemspec file :

spec.add_runtime_dependency "numbers_and_words"
spec.add_runtime_dependency "reform"

and is supposed to serve apps that use Ruby 2.1. When running the test suite for the gem out of a Rails app, it fetches ActiveSupport 5.0.0, which asks for Ruby 2.2.2. Probably an inevitable caveat, requiring a forced ActiveSupport version on my end, even though my application doesn't depend on it

[dblock]

If you want a lower version of AS than 5, you should tell your app in Gemfile with gem 'activesupport', '~> 4.0' for example, otherwise it always tries to select the most recent one.

I'll close this, it works as designed I believe.

Exactly, you should add that restriction on your Gemfile / .gemspec: http://guides.rubygems.org/patterns/#declaring-dependencies

[dblock]

@jlduran Are you saying we should add it in numbers_and_words? I don't agree. This gem works well with ActiveSupport 5.0, your problem is that it brings a version of Ruby you don't want, no?

No, it was a suggestion for @Koroeskohr's .gemspec file.

He can, either create a Gemfile and restrict AS < 5, even a .ruby-version file to build the gem (this would be a way of doing it without including the dependency in his .gemspec file) or – the proper way – forcing the dependency on his .gemspec file, after all, is his gem that is not compatible with AS 5, even if it does not use AS directly, it is needed by numbers_and_words (imagine I try to include his gem on a Rails 5 project, for instance).

@jlduran @dblock well reading his description again he said 'a gem i work with requires numbers_and_words'. i'm not sure if that means developing an app/project that depends on a gem (that depends on numbers_and_words) or developing a gem (that depends on numbers_and_words). i just tested, and bundle install with a Gemfile that only has numbers_and_words in it on ruby 2.1 does give you an error (Gem::InstallError: activesupport requires Ruby version >= 2.2.2.). so if he is developing an app/project that runs on 2.1 he should just pin AS < 5 himself in his own Gemfile, if he is developing a gem the users of his gem should pin AS < 5 in their own Gemfile.
