Rails中的奇怪错误-缺少帮助程序 [英] Strange error in rails - missing helper
问题描述
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.
I am not sure , but this might be associated with a crashed computer. After restarting (after the crash) I get a missing helper error where the helper name is wrong. Switching branches has no effect on the outcome.
错误是:
缺少帮助程序文件helper//users/xxxx/sites/xxxx/app/helpers/accounts_helper.rb_helper.rb
Missing helper file helpers//users/xxxx/sites/xxxx/app/helpers/accounts_helper.rb_helper.rb
我已经尝试过更新gem，卸载并重新安装rails，检查辅助程序名称以及包含辅助程序的任何位置. Ive还查看了git日志并检查了最近更改的代码.没有运气.
Ive tried updating gems, uninstalled rails and reinstalled, checked helper names and anywhere helpers are included. Ive also reviewed git logs and checked recently changed code. No luck.

推荐答案
这个问题似乎是在最新版本的ruby 2.2.0中引入的.
The problem seems to have been introduced in the latest version of ruby, ruby 2.2.0.
尝试这个实验:
在Rails控制台/或irb中:
in rails console/or irb:
[1] pry(main)>File.expand_path ("./")
=> "/users/xxxx/Sites/xxxx"
并在终端窗口中:
]$ 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.使用查找程序重命名sites目录也可能会起作用，因为先将其重命名为"foobar"，然后再重命名为"sites".
See the different case? If you get that, then deep in the bowels of active support a regex goes south. One fix is to remove the "sites" directory and recreate. It might also work to rename the sites directory using the finder, as rename it to "foobar" and then back to "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)，并且可以正常工作.
And when I was debugging this with another person, it was enough to have a mixed case directory name in the path. We renamed it to 'farknerd' and then back the original, except all lower case, and it worked.
