To Japaneseize error messages with Rails5
Add the following to Gemfile
gem 'rails-i18n', '~> 6.0.0'
Then at the terminal
$ bundle install
When I execute, the following error occurs and installation is not 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.
gem 'rails-i18n', '~> 6.0.0'
The version specification was incorrect.
The above version was for rails 6.
The version of rails this time was rails5, so in that case,
gem 'rails-i18n', '~> 5.1'
If so, OK! !!
afterwards,
$ bundle install
After executing, the installation was successful.
