Paperclip 在检查插件的 rails3 分支后产生此错误.我的 Gemfile 有以下几行:

推荐答案

更新 06-21-10: thoughtbot 版本已修复.

我必须在 class Application < 的末尾将 Paperclip::Railtie.insert 添加到我的 application.rb 中.Rails::Application 使其正常工作.由于官方回购正在运行，我已经删除了我的分叉.希望对某人有所帮助.

I had to add Paperclip::Railtie.insert to my application.rb at the end of class Application < Rails::Application to get it to work correctly. I have deleted my fork since the official repo is working. Hope that helps someone.

您还需要将以下内容添加到您的 Gemfile 中

You will also need to add the following to your Gemfile

gem "paperclip", :git => "http://github.com/thoughtbot/paperclip.git"
