大佬教程收集整理的这篇文章主要介绍了railstutorial.org gems / notiffany-0.1.1 / lib / notiffany / notifier / tmux / client.rb:12:in\”version’：undefined method，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。
我还对错误进行了一些搜索,并提出了关于tmux的评论,但我在Ruby on Rails或Cloud9上没有足够的经验来确定我正在做什么.有人还建议做’捆绑exec rake test’作为替代,但我得到同样的错误：

我没有在Gemfile中看到任何名为notiffany的内容,但我发现它与Guard有关.由于我使用的是教程中指定的特定版本,因此我不确定是否需要修复新版本.
我可能只是没有找到合适的关键字,所以如果以前已经回答过,我会道歉.任何帮助表示赞赏.
