Q&A
Gemfileの内容をご提示おねがいします。
エラー文を見た感じ、古いパッケージバージョンを指定してしまって、依存関係を解決できない状態になっているようです。
Ruby on Rails での環境構築をvagrantでやりましてwebサーバー立ち上げの直前でつまづきました。vagrant/ruby_lessons/myappまでいきサーバー立ち上げするためローカルホストの番号を入力したのですができませんでした。その後bundle installをしようとしたのですがエラー表記が出ました。エラーの表記が出ていてそれを調べながらやってるんですができません。どなたか教えていただけると嬉しいです。
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.

連絡ありがとうございます。
これです。
初期の状態ではできなかったので自分でぐぐりながら少しいじりました。
