Ruby on rails ⇒ rails new booksをインスト

WindowsでRuby on railsの学習を始めました。

Ruby, Rails, SQlite3等のインスト－ル及び設定は完了し
アプリケーション用の雛形となる各種ファイルを自動生成する
為の"rails new books"をコマンドプロンプトで実行しましたがうまくいきません。

発生している問題・エラーメッセージ

該当のソースコード

C:/Ruby31-x64/lib/ruby/gems3.1.0/railties-7.0.4/lib/rails/
generators/rails/app/app_generator.rb:258:in``':No such file
or directory - git config init.dafaultbranch (Errno::ENOENT)

C:/のいろんな場所でrails new booksをコマンドプロンプトで実行
しましたが結果は変わらずでした。

よろしくお願いします。
