Ruby中的封送字符串

我遇到了使用Capistrano的错误。我已经缩小的错误逐字这行代码：Ruby中的封送字符串

puts message

当“消息”是，有来自通过网络-SSH一个删除服务器的字符串。

所以我试图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)，将它给我的东西复制/粘贴到脚本中的Marshal.load(...)中。

但是当我这样做，我的单个.rb文件完美地工作。

所以我检查了我的应用程序，当我执政时，立即解开capistrano中的字符串，它的工作原理。因此，编组中的一些东西正在迷失，并且阻止我可靠地复制错误。

我使用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]

这正好为比但它只是一堆动态方法调用的较长的错误。

错误还介绍了关于puts "#{message}"和puts "#{message.strip}"不同的错误

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。

长话短说：如果你要留在1.6.4

编辑使用str = Marshal.load(Marshal.dump(str))：1.6.5已经发布，包含此修复程序。

这可能是该消息是另一种Ruby对象中的类http://www.ruby-doc.org/core/IO.html红宝石IO家庭赋予的，而不是一个字符串，但某种缓冲自带来自ssh会话。尝试Marshal.dump(message.to_s)，或者将message.class确认它实际是什么。

我确认它是类String。 – Lelon

英联邦英语发音者应该注意，它是'Marshal'，而不是'Marshall'，因为Ruby（和日语程序员）使用美式英语。 –
