[RUBY] Ajouter gem'rails-i18n ',' ~> 6.0.0 'et que faire si l'installation du bundle donne une erreur

Apparence d'erreur

Pour traduire les messages d'erreur en japonais avec Rails5 Ajoutez ce qui suit à Gemfile

gem 'rails-i18n', '~> 6.0.0'

Puis au terminal

$ bundle install

Lorsque j'exécute, l'erreur suivante se produit et l'installation n'est pas possible.

The dependency tzinfo-data (>= 0) will be unused by any of the platforms Bundler is installing for. Bundler is installing for ruby but the dependency is only for x86-mingw32, x86-mswin32, x64-mingw32, java. To add those platforms to the bundle, run `bundle lock --add-platform x86-mingw32 x86-mswin32 x64-mingw32 java`.

Resolving dependencies...
Bundler could not find compatible versions for gem "railties":
  In snapshot (Gemfile.lock):
    railties (= 5.2.4.3)

  In Gemfile:
    coffee-rails (~> 4.2) was resolved to 4.2.2, which depends on
      railties (>= 4.0.0)

    rails (~> 5.2.4, >= 5.2.4.3) was resolved to 5.2.4.3, which depends on
      railties (= 5.2.4.3)

    rails-i18n (~> 6.0.0) was resolved to 6.0.0, which depends on
      railties (>= 6.0.0, < 7)

    sass-rails (~> 5.0) was resolved to 5.1.0, which depends on
      railties (>= 5.2.0)

    web-console (>= 3.3.0) was resolved to 3.7.0, which depends on
      railties (>= 5.0)

Running `bundle update` will rebuild your snapshot from scratch, using only
the gems in your Gemfile, which may resolve the conflict.

Cause d'erreur

gem 'rails-i18n', '~> 6.0.0'

La spécification de version était incorrecte. La version ci-dessus était pour «rails 6».

Solution

La version de rails cette fois était rails5, donc dans ce cas,

gem 'rails-i18n', '~> 5.1'

Si oui, OK! !!

ensuite,

$ bundle install

Après l'exécution, l'installation a réussi.
