Detect the path used to require a file?

Ruby
1

Hi all,

I’m having a problem in which a file is being required twice, using
slightly different paths, and I want to track down where this is
happening. Is there a way I can print out the path used to require a
given file?

Thanks!

Create a load monitor, eg.

alias old_require require
def require(path)
puts path, caller, “—”
old_require(path)
end

In most Ruby implementations the FILE constant will be different
depending on how the file was loaded. Notably, it will reflect the path
used to load the file.

== test.rb ==
puts FILE

ruby -r test.rb -e ‘’
./test.rb

ruby -r /home/user/temp/test.rb
/home/user/temp/test.rb
