【问题描述】：

我从 2.3.3 更新到 2.3.5 的字符串到数组的错误，现在当我尝试调用 Model.image.reprocess 时！我收到以下错误。这是我的代码中的东西还是回形针中的东西？或者在我上传的图片中？

【解决方案1】：

这是paperclip 的一个错误。恢复到以前的版本，你会没事的。这真的让我把头发拉了几天。 :)

【讨论】：

哼。它在主分支中固定吗？我可能只需要检查一下。如果我将 git repo 放入生产代码中，就不会出现任何问题，对吧？ ;)
看起来它实际上已在 3 天前修复，因此更新 gem 应该可以工作。它教会我如何指定一个 gem 版本，因为它在 heroku 上破坏了我的生产应用程序。 :)
您使用的是什么版本的 gem？我在 2.3.5 上，它正在对我这样做。
哦，这看起来像是一个新错误。 2.3.4 中引入了 to_file 字符串到数组的错误； 2.3.3 在 Rails 2.3 上对我来说工作正常。

【解决方案2】：

不是答案，只是确认我有同样的问题。我在 Rails 3 上并尝试使用 Paperclip 2.3.5、2.3.4 和 2.3.3 在调用 reprocess 时，一切都无济于事，不断收到与 @Reactor5 相同的错误

有什么想法吗？

编辑我对此进行了更多调查。 Paperclip 和 Ruby 1.9.2 似乎有问题仍然不知道究竟是什么原因造成的，但切换到 Ruby 1.8.7 为我解决了这个问题。
