Question

我有一个加载jruby的可执行jar。安装程序将jar和一些预先打包的jar库（包括完整的jruby和一些gem）放入安装位置。

除非在Windows中将jar安装到名称中包含空格的文件夹中，否则一切正常。当Jruby从一个罐装宝石中遇到一个简单的“需求”时，Jruby失败了（如果重要的话，在statemachine gem中需要“single singleton”）。

这不是什么大问题，但我需要从程序文件下运行jar。希望有人在那里解决了这个问题：）

这可能是一个错误。你用什么软件来创建可执行jar？什么版本的JRuby？我们过去曾经处理过带有空间错误的文件名，但肯定会有其他错误。你可以在http://bugs.jruby.org提交错误吗？感谢。

为什么加载jruby的可执行jar不会在名称中包含空格的文件夹下运行，例如程序文件？
