Ruby require not finding all files - ruby

Question

I've done some research and nothing quite hits on my issue...
I'm building a gem so I have a directory structure like this
root/ - lib/ - mygem/ - cli.rb
- version.rb
- xmltemplates.rb
- mygem.rb
- bin/
It's a thor app so in cli.rb I have:
require 'thor'
require 'mygem/version'
require 'mygem/xmltemplates'
module MyGem
#STUFF
end
And in vesrion.rb:
module MyGem
VERSION = '0.1.0'
end
and in xmltemplates.rb:
module MyGem
MY_TEMPLATE = 'TEST'
end
I was getting errors when trying to compile with as a gem so I decided to play with it in irb.
So for this test I did cd lib to make myself local to the lib directory.

1.9.3-p392 :005 > require 'mygem/cli'

1.9.3-p392 :009 > require 'mygem/version'
=> true
1.9.3-p392 :010 > MyGem::VERSION
=> "0.1.0"
So it boils down to this: Is there any reason that mygem/version would load find and mygem.xmltemplates would not? I've checked permissions on the files as well and they are all identical.
Some of the previous posts I've read mentioned require_relative, but that didn't work for me and it seems like if that was it I would not have been able to load cli.rb or version.rb.

When working with gems it's important that your .gemspec file is up to date. The gem loader uses this to find files. Perhaps you haven't added xmltemplates to that spec yet?
If you're trying to diagnose loading problems, always check $LOAD_PATH to be sure your lib/ is in there. If it isn't, you will get LoadError type exceptions due to missing files.
