ruby-on-rails - 启动 Rails 服务器时 ImageMagick 的警告

coder 2025-07-27 原文

最近，当我启动我的 Rails 服务器时，我收到了一长串警告。虽然它不影响我的应用程序，但我想知道如何解决这些警告。我的估计是 imagemagick 以某种方式被调用了两次？

当我在警告前后检查我的 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 和 imagemagick 有关系吗？

最佳答案

在我的例子中，停止在我的 gemfile 中要求它是有效的:

gem 'rmagick', require: false
