我正在使用 ruby 1.9.2 开发 ubuntu 12.10：

ruby -v
ruby 1.9.2p320 (2012-04-20 revision 35421) [i686-linux]

ruby 1.9.2-p290 也发生了错误，但在 1.9.3 中它可以正常工作。不幸的是，我无法升级 ruby 版本，因为我正在使用旧版 Rails 应用程序：

宝石文件：

我尝试过几次重新安装 ruby 版本，但没有帮助。

任何帮助将不胜感激！

我没有看到针对 Ubuntu 报告的问题，但我确实看到了针对 OS X Lion的问题。您可能会考虑找出针对 1.9.2 报告问题的确切位置，并尝试查看社区中是否有人可以为您提供有关如何获取错误报告的更多指导 (a) 验证为实际错误而不是由某些原因引起否则，以及 (b) 如果确实得到验证，则在何处以及如何提交错误。

我不认为您应该直接在 backport 页面中创建问题，但至少在这里参考的是 1.9.2 backport 列表中的问题列表。
