Rails 3 - psych.rb - 无法解析 YAML

Question

在集成backgroundrb-rails3时，出现以下错误，

~/.rvm/rubies/ruby-1.9.2-p290/lib/ruby/1.9.1/psych.rb:148:in `parse': couldn't parse YAML at line 8 column 22 (Psych::SyntaxError)

from ~/.rvm/gems/ruby-1.9.2-p290/bin/packet_worker_runner:19:in `<main>'

我在堆栈中发现了一个类似问题溢出并且接受的答案对我有用。

我不想使用 Syck，如何使用 Psych 修复它？两者的 yml 格式有什么区别吗？由于回溯没有指向任何 yaml 文件，我如何调试更多？

非常感谢任何帮助...

好吧，看起来 Psych 无法从默认配置中解析此特定行：

:trigger_args: */5 * * * * * *

将条件括在引号中应该可以修复它：

:trigger_args: "*/5 * * * * * *"

您可以将默认配置复制到您的 config 文件夹中并在其中进行此更改。这是要使用的确切文件： https://raw.github .com/mtylty/backgroundrb-rails3/master/config/backgroundrb.yml
