I’m using the One-click 1.8.7rc2 Ruby Windows installer, everything
has been working fine up till now, when i want to start getting into
testing, i got this error, any reason why?

Can someone tell me how to solve this?

The first tip is scan thru all that barf for the first line in code you
wrote,
not library code. (Not that library code is bug-free, but you just have
better
odds to understand it!)

     ... 24 levels...

However, you must run that test again, maybe with ruby
test/unit/whatever.rb, so
the pin-head system won’t elide the filenames from your own code!

Thanks for that, i don’t recall using any jpgs, but its definitely
worth a try. will post back soon with results.

I had the same error running my tests. It was working fine then
stopped working with the above error. Unfortunately, the trace is not
real helpful because the error was occurring in environment.rb …
template_handlers.rb … erb.rb. Rather than debug Rails or Ruby I
went through a process of elimination to find what file was causing
the issue.

I found a .jpg file in one of my view folders that if removed allowed
the test to complete properly. Per where the error occurring in
template_handlers, while I don’t know why it puked on this file, it
did relate to a view folder.

I don’t recall any documentation restricting .jpg files from view
folders but maybe I missed something.

I hope this helps.
