【问题描述】：

尝试在 railstutorial.org 上学习 Rails 教程。我目前处于教程的测试部分，并且在执行测试时不断出现错误。我使用“生成静态页面控制器”命令创建的测试文件原样，我根本没有修改它。当我输入命令“rails test”时，出现此错误：

/Users/user/.rvm/gems/ruby-2.3.0/gems/actionpack-5.0.0.1/lib/abstract_controller/helpers.rb:152:in `rescue in block in modules_for_helpers'：缺少帮助文件帮助程序//users/user/programming/odin/rails/sample_app/app/helpers/application_helper.rb_helper.rb (AbstractController::Helpers::MissingHelperError)

这是追溯：

如果这被格式化并询问不正确或者我没有道歉，任何帮助将不胜感激，我绝对难倒。 这是 github 仓库：https://github.com/JDjedi/sample_app

Rails 版本是 5.0，ruby 版本是 2.3.0p0

【参考方案1】：

application_helper.rb_helper.rb - 你是这样称呼你的助手的吗？ .rb 是一个扩展。因此，您能否将帮助文件的名称更改为application_helper.rb，看看是否可行？

编辑：

你看过这个问题吗？ Rails: AbstractController::Helpers::MissingHelperError - Missing helper file application_helper.rb_helper.rb

这似乎是一个可行的答案：https://***.com/a/28269245/1010826

只需将根文件夹重命名为相同的名称。不过不知道为什么会这样：)

【讨论】：

在目录中写为'application_helper.rb'。我将在原始帖子中提供对 github 存储库的扩展。

原谅我的无知，但我还是不明白
