我在使用 Capistrano 时遇到了一个错误。我已将错误范围缩小到这行代码：

puts message

其中“message”是通过 net-ssh 来自删除服务器的字符串。

所以我正在尝试创建一个重现此错误的单个 .rb 文件。应该很容易......我只是Marshal.dump(message)将它给我的内容复制/粘贴到Marshal.load(...)我的脚本中。

但是当我这样做时，我的单个 .rb 文件可以完美运行。

所以我检查了我的应用程序，当我在 capistrano 中编组并立即解组字符串时，它可以工作。所以有些东西在编组中丢失了，它阻止我可靠地复制错误。

我正在使用 jruby：

jruby 1.6.4 (ruby-1.9.2-p136) (2011-08-23 17ea768) (Java HotSpot(TM) Client VM 1.6.0_26) [Windows 7-x86-java]

put 上的错误

它持续的时间比这更长，但它只是一堆动态方法调用。

该错误还会在puts "#{message}"和puts "#{message.strip}"

这是 JRuby 1.6.4 中的一个错误。它已在 1_6 分支中修复，应该在 1.6.5 版本中修复。

你可以在这里读更多关于它的内容：

https://jira.codehaus.org/browse/JRUBY-6116

长话短说：str = Marshal.load(Marshal.dump(str))如果您想继续使用 1.6.4，请使用

编辑：1.6.5 已发布并包含此修复。

消息可能是在 ruby​​ IO 系列类http://www.ruby-doc.org/core/IO.html中授予的另一种 ruby​​ 对象，而不是字符串，而是某种来自SSH 会话。尝试Marshal.dump(message.to_s)，或 putsmessage.class以验证它实际上是什么。
