rake testを実行できません。Rails

Question

私はMichael Hartl（chapter 3）のRailsチュートリアルに従っています。しかし、のGemfileを編集してrake testを実行すると、railsはこの行に application configというファイルを作成するように指示しました。私はそれをやったし、もう一度bundle exec rake testを実行し、ここでエラーメッセージがあります：

/home/ys/workspace/sample_app/db/schema.rb doesn't exist yet. Run `rake db:migrate` to create it, then try again. If you do not intend to use a database, you should instead alter /home/ys/workspace/sample_app/config/application.rb to limit the frameworks that will be loaded.

私はその後、rake db:migrateに進み、再びすくいテストを実行します。

を私が推測することができますすべてに問題があるということです私がbundle installを実行したとき、私が2.3.0から2.3.1にアップグレードしたので、先日、レールコンソールがバグについて苦情を申し立てました。 これを解決するにはどうすればよいですか？

https://github.com/guard/guard-minitest

あなたの宝石のファイルにガード宝石を追加します。
