當我在新創建的rails項目上運行rails server時，我總是收到以下錯誤消息。我通過運行命令rails new toy_app來創建它。Ruby on Rails`method_missing'：undefined method`active_record'
請指導我如何解決我的問題。我有另一個鐵軌項目，我可以運行rails server。在我的新項目中是不可能的。

您需要'Gemfile'，並且需要運行'bundle install --without production'（第一次）。 –
你可以請你發佈你的'config/application.rb'嗎？ – spickermann
我有一個寶石文件，我沒有運行捆綁安裝 - 沒有生產 –
