Question

成功升级到Ruby 2.0.0的稳定版本之后（耶！）我决定继续我的Koans 启蒙之路。但是，当我像往常一样在koans文件夹中运行rake命令时，我收到此错误：

rake
cd koans

我今天也从GitHub安装了一个全新的Koans批次，以确保这不是我的问题。对我来说都没有用！ 1.9.3仍然运行良好。值得注意的是，我还通过RVM安装了Ruby 2.0。我确保在这之前更新到最新的RVM。

什么似乎是问题？

有一个拉取请求要解决此问题，但尚未接受：https://github.com/neo/ruby_koans/pull/84

目前，您可以将src/edgecase.rb的第149行编辑为：

in_ruby_version("1.9", "2.0") do

Ruby Koans与Ruby 2.0.0不兼容？
