【问题描述】：

我正在运行一个 JRUBY 应用程序。偶然发现了一个叫做工头的伟大宝石： https://github.com/ddollar/foreman

但是我发现 - JVM 不支持分叉：

这很遗憾，因为我喜欢经营 Foreman 的想法。有谁知道上述问题的解决方法，或者在 JRUBY 环境中运行的替代方法

【问题讨论】：

如果您想修补工头，使用 Spoon gem 可能是一个不错的选择。

【解决方案1】：

感谢这个 gem 的创造者的出色工作，现在 Jruby 中可以使用它

https://github.com/ddollar/foreman

在 Jruby 1.6.6 中运行良好

其他几个选项是 RVM 包装器和 Guard::Process，如下所述：http://www.without-brains.net/blog/2011/09/21/using-foreman-to-run-jruby-with-rvm-and-mri/
