Bundle complete! 20 Gemfile dependencies, 68 gems now installed.
Gems in the groups development and test were not installed.
Bundled gems are installed into `./vendor/bundle`
Post-install message from i18n:
HEADS UP! i18n 1.1 changed fallbacks to exclude default locale.
But that may break your application.
If you are upgrading your Rails application from an older version of Rails:
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.
If you are starting a NEW Rails application, you can ignore this notice.
For more info see:
https://github.com/svenfuchs/i18n/releases/tag/v1.1.0
Post-install message from sass:
Ruby Sass has reached end-of-life and should no longer be used.
* If you use Sass as a command-line tool, we recommend using Dart Sass, the new
primary implementation: https://sass-lang.com/install
* If you use Sass as a plug-in for a Ruby web framework, we recommend using the
sassc gem: https://github.com/sass/sassc-ruby#readme
* For more details, please refer to the Sass blog:
