我有一个 Ruby on Rails 应用程序我正在使用 Ruby 1.9 和 Rails 2.3.4，我希望用户上传视频，所以我安装了 Paperclip gem，但我从 Rack 收到了这个错误。它说它是“无效的字节序列”的事实让我怀疑它来自 Ruby 1.9。

有任何想法吗？

谢谢，

谭

看起来这里有一个答案：

http://rubynyc.wordpress.com/ruby-1-9-1/paperclip-triggering-a-invalid-byte-sequence-in-us-ascii/

本质上，修复方法是卸载 Rails 附带的 Rack 版本，然后从 github 重新安装 gem。当然，您可能想先在另一台机器上尝试一下... :-)
