這是我第一次在生產環境中啓動rails應用程序。我第一次運行rails server -e production，然後必須得到密鑰。之後我跑了這條線bundle exec rake assets:precompile db:migrate RAILS_ENV=production。有一次，我跑這條線我跑rails server -e production一次我在終端得到了以下錯誤（見最後4行），在瀏覽器中的404錯誤頁面沿：無法在本地生產環境中啓動rails - Rails 5

當我去是行這裏給了一個錯誤，他們分別是：

在開發中，這工作正常。我無法弄清楚爲什麼這些行給我一個錯誤，並且不允許Web應用程序啓動，他們看起來是正確的，並讓我看到我在開發模式時需要的外觀。
