Jruby - 工头 Gem 未运行

Question

我正在运行 JRUBY 应用程序。并偶然发现了一颗名为 Foreman 的伟大宝石： https://github.com/ddollar/foreman

但是我发现 - JVM不支持分叉：

这是一种耻辱，因为我喜欢管理福尔曼的想法。有谁知道解决上述问题的方法，或者在 JRUBY 环境中运行的替代方案

Answer 1

感谢这个 gem 的创建者的出色工作，现在可以在 Jruby

https://github.com/ddollar 中使用/foreman

在 Jruby 1.6.6 中运行良好

Answer 2

另外几个选项是 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/
