Answer 1

将gem 'paperclip', github: 'thoughtbot/paperclip'添加到您的gemfile。

信用证转到：https://github.com/thoughtbot/paperclip/issues/1495

Answer 2

我遇到了同样的问题。我有一个在我的gemfile中指定的paperclip版本，它太旧了，无法与我的其他版本一起使用。也许只需用

之类的东西更新gemfile的版本号

gem＆＃39; paperclip＆＃39;，＆＃39;〜＆gt; 4.3＆＃39;

请相信你 $ bundle install 更新版本后，在你说之前 $ rails生成回形针图像
