ruby-on-rails-4 - Rails中的奇怪错误-缺少帮助程序

我不确定，但这可能与崩溃的计算机有关。重新启动后(崩溃后)，我收到一个缺少的帮助程序错误，其中的帮助程序名称错误。切换分支对结果没有影响。

错误是:

Missing helper file helpers//users/xxxx/sites/xxxx/app/helpers/accounts_helper.rb_helper.rb



Ive尝试了更新gem，卸载了rails并重新安装，检查了helper名称以及包括helper的任何位置。 Ive还查看了git日志并检查了最近更改的代码。没有运气。

最佳答案

这个问题似乎是在最新版本的ruby 2.2.0中引入的。

试试这个实验:

在Rails控制台/或irb中:

[1] pry(main)>File.expand_path ("./") 
=> "/users/xxxx/Sites/xxxx"

在终端窗口中: 
]$ pwd
/users/xxxx/sites/xxxx

看到不同的情况了吗？如果您明白了，那么积极支持的根深蒂固，正则表达式就会南下。一种解决方法是删除“站点”目录并重新创建。使用查找程序将站点目录重命名也可以，将其重命名为“foobar”，然后重命名为“sites”。

当我与另一个人进行调试时，在路径中包含大小写混合的目录名就足够了。我们将其重命名为“farknerd”，然后恢复原始格式(除所有小写字母之外)，并且它可以正常工作。
