carrierwave.rb:45:in block in <class:Railtie>': undefined method include?'

[MateoLa]

Hello.
Everything was ok until today when I exec bundle update.
Now I can't start rails.
I get this error:
/var/lib/gems/2.4.0/gems/carrierwave-1.2.0/lib/carrierwave.rb:45:in block in <class:Railtie>': undefined method include?' for 🇪🇸Symbol (NoMethodError)

In app/config/environments/.rb I have: " config.i18n.available_locales = :es"
In app/config/initializers/locale.rb I have:
# config/initializers/locale.rb
I18n.load_path += Dir[Rails.root.join('lib', 'locales', '.{rb,yml}')]
I18n.available_locales = [:en, :es]
I18n.default_locale = :es

In app/lib/locales I have 4 files: es.yml, en.yml, devise.en.yml, devise.es.yml
In the es.yml file I made the corrections for carrierwave error messages.

I read the line 45 in carrierwave.rb.
Is an if conditional so it can't figure out how it is throwing the undefined method error for an include? no matters the :es symbol.

I am in:
ruby 2.4.1p111 (2017-03-22 revision 58053) [x86_64-linux-gnu]
Rails 5.1.4

(I made a test moving locales under app/config/locales/... but the same happens)

I appreciate any help. Thanks, Mateo.

Sorry for the issue, please see if the fix 796ddb0 works. If it does, I'll push another release.

Yes. This fix works. Thank you M.
