エラーの内容を見ると、既に作成されたアプリケーション myapp を再度指定しているように見えます。rails new を実行したdirectoryにmyappというdirectoryが存在しませんか？
その場合の解決方法
- rails new はやめ、既存のmyappを用いる
- 既存のmyappをdirectoryごと削除してからnewする
- 既存のmuappの名前を変更してからnewする
- myappではないべつのアプリケーションでnewする

別の名前でnewしてみました。
上記のエラーの解決法があれば引き続きぜひ教えていただきたいです＞＜
rails new は成功して、後処理のbundle install も成功しています
Bundle complete! 17 Gemfile dependencies, 59 gems now installed. ってあります
このあとの作業は rails new ではなく、そのdirectoryに移って行って下さい
その後の処理の springの起動で失敗していますが、エラーメッセージからはinstallされていないようです。Gemfileに記載されているか確認して、なければ追加して bundle install してください。
うまく行かない時は、Gemfileとエラーメッセージを載せて下さい。
が、
私はこれからでかけて深夜までもどらないので、今日は私はここまでです。
