最近我有一長串警告，當我啓動我的導軌服務器。雖然它不影響我的應用程序，但我想知道如何解決警告。我的估計是imagemagick不知何故被稱爲兩次？ImageMagick的警告當我啓動我的導軌服務器
當我檢查我的git日誌之前和之後的警告。我想知道如何解決這個問題。
- bcrypt-ruby (3.1.2)
- better_errors (1.0.1)
+ bcrypt (3.1.7)
+ bcrypt-ruby (3.1.5)
- bcrypt (>= 3.1.3)
+ better_errors (1.1.0)
bcrypt與imagemagick有什麼關係？

在短暫的一瞥，它看起來真的像你加載ImageMagick的兩倍。它是否包含在寶石中，然後又在其他地方使用？ –
它看起來像你第一次做'需要'rmagick''，然後'需要'RMagick''。 Ruby會將它們視爲不同的文件，但在Mac上，文件系統不區分大小寫，因此它們是相同的文件。它應該是'RMagick' - 你可能需要在''Gemfile''中加入：：require =>'RMagick'。我不知道使用'action_dispatch'的前兩行發生了什麼，所以也許它是別的。 – matt
