loading modules path error on running javascript test with testee and steal

I am writing test with funcunit and running it with testee. I can run the test successfully on my local machine, but when I run it on jenkins, it has loading error.

testee:html-injector injecting scripts into file +783ms /node_modules/testee/node_modules/launchpad/node_modules/dtrace-provider/package.json

steal-qunit.js, jquery.js, and funcunit.js should loaded from node_modules directory, but testee is looking at root directory to find them. Can anyone help me out for this issue?

The main test javascript file looks like:

var QUnit = require('steal-qunit'),
    F = require('funcunit');

And each test file has this at the top of the file.

require('jquery');
require('steal-qunit');
