Bundle complete! 2 Gemfile dependencies, 41 gems now installed.
Gems in the groups development and test were not installed.
Use `bundle show [gemname]` to see where a bundled gem is installed.
Post-install message from i18n:

HEADS UP! i18n 1.1 changed fallbacks to exclude default locale.
But that may break your application.

Please check your Rails app for 'config.i18n.fallbacks = true'.
If you're using I18n (>= 1.1.0) and Rails (< 5.2.2), this should be
'config.i18n.fallbacks = [I18n.default_locale]'.
If not, fallbacks will be broken in your app by I18n 1.1.x.
