每当我运行以下代码时，我都会在终端上不断收到这些错误。

rake test  or bundle exec rake test

【问题讨论】：

显示导致此问题的测试代码。
看起来guard gem 没有安装；尝试运行bundle install。
我已经这样做了，但仍然尝试了一遍。仍然得到同样的错误。以及如何安装保护 gem 我只是将 gem 'guard' 添加到我的 gemfile 中..
@RailsOuter 这是它们仍然默认的代码没有添加任何内容 require 'test_helper' class StaticPagesControllerTest
@PrakashMurthy .. 感谢它的工作，我将 gem 文件添加到开发组并且它工作了......但是如果其他项目最好将保护 gem 添加到开发或测试环境中?

【解决方案1】：

看起来guard 没有安装/包含在 Gemfile 中。如果 Gemfile 不存在，请将其包含在 Gemfile 中。并运行bundle install。

请参阅http://railscasts.com/episodes/264-guard 了解如何使用守卫。 https://github.com/guard/guard 也是不错的资源。
