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

一切正常，除了在 Windows 中，当 jar 安装到名称中带有空格的文件夹中时。当 Jruby 遇到来自 jar 打包的 gem 之一的简单“require”（如果重要的话，状态机 gem 中的“require singleton”）时，它会失败。

这不是什么大问题，但我需要 jar 从程序文件下运行。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？我们过去处理过文件名和空格的错误，但肯定还有其他错误。您可以在http://bugs.jruby.org提交错误吗？谢谢。
