Cucumber 铁红宝石和黄瓜

在使用IronRuby 1.0 RC1运行Cucumber 0.5.1时，出现以下错误：

IronRuby.Libraries.Yaml:0:in `ScanAnchor': while scanning an alias: expected alphabetic or numeric character, but found

我不知道现在该怎么办。 我正在尝试运行示例cumber特性

黄瓜特性（运行良好）

icucumber功能（抛出此错误）

它与languages.yml文件有关。 该文件正在第10行的platform.rb文件中加载，这是cucumber gem的一部分。 我尝试的是：

正在删除文件，但仅此而已 导致“找不到文件”错误

文件中只留下英文。 那是行不通的

清除文件 在所有内容中。给了一些零分 方法错误

您可能想在IronRuby邮件列表上发布该问题，以获取更多信息。这可能是一个错误。
