Question

我正在运行JRUBY应用。并且偶然发现了一颗叫做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，因为我喜欢运行Foreman的想法。有没有人知道解决上述问题，或者在JRUBY环境中运行的替代方案

Answer 1

感谢这个宝石创作者的精彩作品，现在可以在Jruby中找到

https://github.com/ddollar/foreman

在Jruby 1.6.6中正常运行

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/

Jruby - Foreman Gem没有跑
