对此有何线索？

UPDATE

我的宝石文件：

gem "rmagick", "~> 2.13.1" 
gem 'link_thumbnailer' 

Answer 1

常数被重新初始化的原因可能是因为rmagick宝石被加载两次：一次是为link_thumbnailer的依赖关系（在你的Gemfile），和一次是因为你明确地列出'rmagick'作为Gemfile需求。

尝试删除您的Gemfile，这将是无论如何加载过程中的rmagick条目您使用link_thumbnailer

Answer 2

而不是在你的Gemfile去除rmagick宝石，你可以替换相应的行：

gem 'rmagick', require: false
