ruby – 如何在1.9.2上安装SystemTimer？

Ruby 前端之家
前端之家收集整理的这篇文章主要介绍了ruby – 如何在1.9.2上安装SystemTimer？，前端之家小编觉得挺不错的，现在分享给大家，也给大家做个参考。
我刚刚将我的应用程序从1.8.7升级到1.9.2使用RVM,并且必须添加RubyGems和Bundler,运行捆绑安装,并让除了SystemTimer之外的一切工作. Google-fu什么也没有返回,我看到其他人在1.9中遇到了问题,但有些已经让它工作了.有任何想法吗？

解决方法

据我所知,SystemTimer与ruby 1.9无关,不应与此版本一起使用.

“在Ruby 1.9中使用这个宝石是无用的,没有任何意义！系统定时器正在努力解决Ruby 1.8(MRI)中使用的”绿线程“模型的一些限制,更多细节见http://ph7spot.com/musings/system-timer.
