Rails錯誤：Unintialized常量Sass :: Plugin（NameError）

Question

使用腳手架創建一些代碼後，我遇到了一個奇怪的錯誤。現在，任何新的生成或銷燬命令都會出現以下錯誤。

$ rails destroy scaffold Plugin

Answer 1

按照錯誤日誌中，有兩個選擇，你可以嘗試：

1) Comment one line something like gem 'sass' in Gemfile due to name conflict of Plugin 
2) Configure Sass gem properly 

那麼很可能你就可以正常運行新生成並摧毀命令。
