要求辛纳屈宝石的错误

我很难让辛纳特拉运行在我的本地设置，Ubuntu业力9.10。当我需要“sinatra”时，引发的错误是：
NoMethodError: undefined method `[]' for nil:NilClass
from /usr/local/lib/ruby/gems/1.8/gems/sinatra-1.0/lib/sinatra/base.rb:891:in `compile'

from (irb):2
from :0我试过：
- Uninstalling/reinstalling Sinatra
- Updating all gems
- 确保所有依赖项都存在(齿条)
有什么想法吗？非常感谢您的时间和帮助！

在Linux上，这显然只是一个1.8头的问题。这与正则表达式匹配有关。如果您看一下代码：path确实与/((:\w+)|[\*#{special_chars.join}])/匹配，但是$2是nil，尽管它应该是一个字符串。
我建议现在换一下你的红宝石版本。
