最近我有一长串警告，当我启动我的导轨服务器。虽然它不影响我的应用程序，但我想知道如何解决警告。我的估计是imagemagick不知何故被称为两次？ImageMagick的警告当我启动我的导轨服务器
当我检查我的git日志之前和之后的警告。我想知道如何解决这个问题。
- 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与imagemagick有什么关系？

在短暂的一瞥，它看起来真的像你加载ImageMagick的两倍。它是否包含在宝石中，然后又在其他地方使用？ –
它看起来像你第一次做'需要'rmagick''，然后'需要'RMagick''。 Ruby会将它们视为不同的文件，但在Mac上，文件系统不区分大小写，因此它们是相同的文件。它应该是'RMagick' - 你可能需要在''Gemfile''中加入：：require =>'RMagick'。我不知道使用'action_dispatch'的前两行发生了什么，所以也许它是别的。 – matt
你能弄清楚这一点吗？获取相同的错误 – kibaekr
