你希望我們能夠真正閱讀嗎？請重新格式化爲清晰的內容。編輯有很多工具可以幫助你解決這個問題。 –

你還沒有問一個問題，但我想你有一些問題， 'class_attribute' 是不確定的。

我不確定（懶得檢查;-)，但可能'class_attribute'已被添加到Rails 3中。您有Rails 2和一個回形針gem。

你可以嘗試使用這種寶石的舊版本 - 只是檢查哪一個是使用Rails兼容2.

UPDATE：

正如你可以在評論閱讀，大衛發現你的一個版本有這個方法定義的Rails。所以，你有兩個選擇：升級Rails至少2.3.9，或降級回形針。

你是對的：'class_attribute'最初被添加到Rails 3.但是，它被移植到了Rails 2.3.9，因此可能是OP的一個選項。 –

那個問題現在解決了我在獲取嘗試上傳圖像時出現以下錯誤[回形針]/usr/bin/identify'-format％wx％h：file'2>/dev/null [paperclip]處理時收到錯誤：＃ [回形針]/usr/bin/identify'-format％wx％h：file '2>/dev/null [回形針]處理過程中收到錯誤：＃
