Answer 1

你没有问过一个问题，但我认为你有一些'class_attribute'未定义的问题。

我不确定（懒得检查;-)，但有可能在Rails 3中添加了'class_attribute'。你有Rails 2和回形针gem。

您可以尝试使用此gem的旧版本 - 只需检查哪一个与Rails 2兼容。

更新：

正如您在评论中所读到的，David找到了一个定义了此方法的Rails版本。因此，您有两种选择：将Rails升级到至少2.3.9，或降级回形针。

添加Paperclip.options [：command_path] =“/ usr / local / bin /”后的回形针问题
