rails　のインストールで失敗します。

ruby のインストールは成功したのですが、
railsのインストールで失敗します。

理由が分かりません。

CMDの出力を一通りコピペします。

すみませんが、どなたかご教授願います。

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

あなたと同じバージョンの組み合わせで試してみましたが特に問題なくrailsアプリができました。
bundleインストール時に、sass-rails、webdriversの依存関係でエラーが出たので
Gemfileを修正したくらいです。

ruby 2.6.6p146
Rails 5.2.3

あなたの環境構築、インストール手順を見直してみてください。
