使用nailgun和spork在JRuby和Rails 2.3.10上尝试加快rspec 1.2测试时出错

我最近开始在Rails2.3WebApp中使用JRuby。从那以后，我的rspec测试一直很慢。。。自从我切换到JRuby后，测试运行的时间太长了

在使用核磁共振成像时，为了更快地运行测试，我从未费心使用spork，但现在我需要加快测试的执行速度

首先，我尝试了spork，但没有成功，因为：

Spork0.9RC支持jruby，但不支持Rails2.3 它只支持rails 3 Spork0.8支持Rails2.3，但不支持jruby，我认为它使用fork，spork-0.8gem不会出现这种情况 安装在jruby上。 我尝试在jruby、rails 2.3和spork 0.9 rc上运行测试，但没有成功，事实上，有一条警告消息说spork 0.9 rc只支持rails>=3.0

然后我尝试了nailgun，我在jruby环境中安装了nailgun gem gem install nailgun，并在我的应用程序根目录下启动了nailgun服务器ruby-ng服务器。 然后我运行一个规范ruby-ng-S spec/lib/importaco_atividades_spec.rb。我第一次执行规范时，它运行得很好，但之后它不断引发RuntimeError:invalid runtime

检查跟踪：

所以我真的被困在这里了。有人知道我如何解决钉子枪的问题吗？如果没有，还有其他选择吗？有可能在jruby和rails 2.3中使用spork吗。。。看起来jruby不喜欢旧版本的Redis gem。更新了我的Resque/Redis gem版本，它成功了。

如果你有代表，请在我的帖子中添加标签钉枪。你怎么知道这是问题所在？
