使用 RSpec2、Ruby1.9.3、Rails 3.1.3 进行防护答案

【问题标题】：Guard w/ RSpec2, Ruby1.9.3, Rails 3.1.3使用 RSpec2、Ruby1.9.3、Rails 3.1.3 进行防护

【问题描述】：

我正在使用 Libnotify 提供的通知成功运行 Guard。

funkdified@funkdified-laptop:~/railsprojects/sample_app$ guard
Guard uses Libnotify to send notifications.
Guard is now watching at '/home/funkdified/railsprojects/sample_app'
Guard::RSpec is running, with RSpec 2!
Running all specs
...

Finished in 0.06053 seconds
3 examples, 0 failures

如果我修改规范文件，我会在终端和弹出通知中收到有关测试结果的警报。如果我修改控制器文件，测试再次正常运行。但是，当我修改 routes.rb 时，整个事情都浮出水面，Guard 停止正常工作并引发错误。有人有什么想法吗？

错误：

忘了提一下，如果我杀死 Guard 并重新启动（在更改 routes.rb 之后），然后 Guard 再次正常执行，这表明测试现在失败了：

funkdified@funkdified-laptop:~/railsprojects/sample_app$ guard
Guard uses Libnotify to send notifications.
Guard is now watching at '/home/funkdified/railsprojects/sample_app'

【解决方案1】：

检查您的spec 目录。它应该有一个用于路由规范的routing 子目录。如果没有，只需创建一个空的。显然，RSpec 在运行rails g rspec:install 时不会在spec 下创建任何子目录，但guard 期望它存在。

【解决方案2】：

我认为您的Guardfile 中可能包含以下行：

watch('config/routes.rb')                           { "spec/routing" }

如果您在 spec/routing 中没有规范，则不要使用您不需要的文件夹。将行更改为：

watch('config/routes.rb')                           { "spec" }

现在，当您更新 routes.rb 文件时，您的所有规范都将运行。
