【中文标题】使用 Spork 和 Guard 时启动错误【英文标题】：Error on start when using Spork and Guard 【发布时间】：2013-01-13 11:10:43 【问题描述】：

这就是问题所在。当添加Guard gem 时，我打电话给Guard 时一切都很好。当我添加 Spork 时，我收到以下错误，它不会影响测试我的测试，但每次我尝试重新启动 Guard 时都会出现此错误。

【问题讨论】：

您没有提供很多信息。但是，看看这个rails cast。 railscasts.com/episodes/285-spork，一步一步来，用 spork 运行 Guard 应该没问题。您还需要什么其他信息？我看了一下 RailsCast；我或多或少地基于它添加了 spork 和 guard 你的规范助手是什么样的？在问题中添加了 spec_helper 添加 spork 后，您运行了 bundle install 吗？请注意也发布您的保护文件 【参考方案1】：

这是一个known issue in guard-spork，您可以通过添加以下内容来使用ChildProcess 的早期版本：

gem 'childprocess', '0.3.6'

到您的 Gemfile 或尝试使用有 fixed the issue 的 guard-spork master 分支，方法是将以下内容添加到您的 Gemfile：

gem 'guard-spork', :github => 'guard/guard-spork'

【讨论】：

太棒了，非常感谢。我最终使用了 gem 'guard-spork', :github => 'guard/guard-spork' 也帮助了我，在 Mac 上运行最新的 Mountain Lion。谢谢。这已在guard-spock 1.4.2 上解决，因此您可以更改为gem 'guard-spork', '1.4.2'。我更新了我的 gemfile 以使用 gem 'guard-spork', '1.4.2' 并解决了这个问题。谢谢@leolobato！我从我的 Gemfile 中的 guard-spork 中删除了版本 (1.2.0)，运行了捆绑更新，将它升级到版本 1.5.0 并为我解决了同样的问题。【参考方案2】：

将 Gemfile 更新为“guard-spork”、“1.4.2”并为我修复了它。
