最近,当我启动rails服务器时,我有一长串警告.虽然它不会影响我的应用程序,但我想知道如何解决警告.我的估计是imagemagick以某种方式被称为两次？
当我在警告之前和之后检查我的git日志时.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有什么关系吗？

解决方法
在我的情况下,停止要求我在我的gemfile工作：
gem 'rmagick',require: false
