最新更新后缺少帮助文件 application_helper.rb_helper.rb答案

【问题标题】：Missing helper file application_helper.rb_helper.rb after newest updates最新更新后缺少帮助文件 application_helper.rb_helper.rb

【问题描述】：

现在刚刚更新到 Xcode 7.0 和 osx 10.10.5，我在运行测试套件时收到了这个 application_helper.rb_helper.rb 错误。我之前遇到过这个错误，并通过更新 rails -v 来修复它。这不是其他人以前遇到的大写错误。尝试回滚到 Xcode 6.4 - 那里没有帮助。

目前使用 ruby 2.2.2 和 Rails 4.2.1。

非常感谢任何帮助。

在本地机器上，当点击root时，我得到这个错误

【问题讨论】：

您能否添加更多关于错误的信息，例如您收到的错误消息以及您收到的代码行？
任何时候加载应用程序，这都是错误。
您能否验证此路径是否与您的项目目录路径匹配（包括区分大小写）？ /users/ryan/turing/homework/2_module/idea_box/app/helpers/，如果某些目录名称不准确，请改为小写
我可以验证。使用 File.expand_path 和 pwd。谢谢
您的目录名是否与上述路径区分大小写？

【解决方案1】：

我在更高版本的 rails 和 ruby 上运行了相同类型的错误消息。原来我在 helper 目录中添加了一个新目录，需要重新启动 spring 才能获取它。

【解决方案2】：

更新了 rvm 以及 ruby (2.2.2) 和 rails (4.2.1)。解决了这个问题。
