Ruby on rails 使用警卫和咆哮运行rspec时出错

我是一名高中生，刚接触RubyonRails，正在尝试用TDD开发Rails4应用程序。我将guard与rspec、spork和growl通知一起使用，但是当我运行guard运行测试时，我得到以下输出，并且测试没有结果：

11 clairehuang:mezzo$ guard

如果我只独立于guard运行rspec，我的测试运行正常并显示输出：

Deprecation Warnings:

RSpec::Core::Configuration#treat_symbols_as_metadata_keys_with_true_values= is deprecated, it is now set to true as default and setting it to false has no effect.


If you need more of the backtrace for any of these deprecations to
identify where to make the necessary changes, you can configure
`config.raise_errors_for_deprecations!`, and it will turn the
deprecation warnings into errors, giving you the full backtrace.

看看这里的答案：看看它是否对你有帮助。@Tarynest:谢谢！所有警告现在都消失了，但rspec不会打印任何输出。还有什么我需要更改的吗？您希望看到什么输出？你知道guard只在更新文件时运行，对吗？我假设您尝试编辑某个文件并保存了它…是的，当我更新测试文件并保存它时，测试将运行，但不会显示“Running:spec/requests/investments\u spec.rb”以外的输出，并且咆哮会说rspec结果失败。确定。。。恐怕我帮不上忙了。
