PROBLEM
Was setting up a rails projects on a windows machine for and the project
required RubyInline. When running rake db:migrate for the first time
RubyInline creates a temp file to ensure it can have access to something
like /tmp/ruby_inline but causes an error:
rake aborted!
File exists - /tmp/ruby_inline3712-0
The problem here is that on windows, doing something like (in order to
emulate this problem)
ruby -r tempfile -e ‘Tempfile.new(“foo”).unlink’
Will not work on Windows (XP Pro).
COMMENTS
Whoever freakin wrote Tempfile#unlink had this little gem in the code:
rescue Errno::EACCES
# may not be able to unlink on Windows; just ignore
So if it can’t delete (unlink) the file it just silently fails - not
cool.
SOLUTION
After reading this post:
http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-core/2848 I
applied the following patch and it worked finally (thanks to Florian
Frank who wrote it).

Can anyone provide any insight on this?
