【Ruby on rails】環境構築にて

Question

前提・実現したいこと

railsの環境構築中にエラーが発生しました。
エラー内容的にbundle installは行ってインストールできれば，エラーが解消されると思ったのですが，解消されず。
色々調べたのですが，解消できなかったので質問いたしました。

発生している問題・エラーメッセージ

xxx@xxxxx:~/Ruby/test_app$ rails s

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`.

何を参考にどこまで進んでいるのでしょうか

Answer 1

気になる点が2つあります。

• rails sを行うには、Rails環境が必要です。rails newは行っていますか？
• Bundlerのインストール先によっては、railsコマンドをbundle exec railsときどうする必要があります。
