Strange error in rails - missing helper

Question

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. Switc

The problem..

For me the same issue with the error

 "missing helper file app/helpers/application_helper.rb_helper.rb"

The app was located in a directory tree

/Users/grantsayer/Documents/Work/recipes

So on conducting the test to show the path, both from within the terminal and within the ruby environment I found the following:

1. Ruby environment

Grants-MacBook-Pro:Recipes grantsayer$ irb

2.2.0 :001 >

2.2.0 :002 > File.expand_path("./") => "/Users/grantsayer/Documents/Work/Recipes"

2. Unix Terminal

Grants-MacBook-Pro:Recipes grantsayer$ pwd /Users/grantsayer/Documents/Work/recipes

At this stage running the rails server and navigating to http://localhost:3000 resulted in the error about a missing application helper. This error, as others have described, appears to be a bug within ruby causing case conversion on the file path.

I solved the issue by renaming the recipes folder to Recipes so that the ruby environment check in irb matched the local filesystem.
