NoMethodError (undefined method `[]'' for nil:NilClass)
I''ve got this error suddenly cropping up. The relevant bit of
development.log is reproduced below. What can I learn from it? My
problem is that none of _my_ code is mentioned in the stack trace.
Any help appreciated.
Thanks,
Gavin

Strange! It would apear that ENV is nil. Can you reproduce this with a simple test?

Re: NoMethodError (undefined method `[]'' for nil:NilClass)
It''s not something that happens all the time, just with my code at the moment, even after a Webrick restart. So a simple test won''t show it. I''ll go digging into the stack trace now; just thought someone may have seen it before. Thanks, Gavin On Thursday, May 5, 2005, 5:40:50 PM, Dee wrote:> Strange! It would apear that ENV is nil.
