require.js is not loading any modules

I am trying to load a module using require.js, and I have the following in my app.js:

require.config({
baseUrl: "js"
});


alert("hello world"); // for debugging

require(['eh2'], function(eh2) {
    alert("nothing here"); // for debugging
});

When I run my application, though, despite the app.js being loaded, the module I'm requiring is never loaded - the "hello world" executes, but the "nothing here" doesn't!

My script tag in the HTML page looks like this:

<script type="text/javascript" src="js/lib/require.js" data-main="app"></script>

And eh2.js is located in the js folder, and it is wrapped in a define statement:

define(["./screens/Screens"], function(screens) {
    return {
        // code here
    };
});

What am I doing wrong? Is require.js silently failing on loading some submodule under screens.js, perhaps?

Here is the code from the Screens module:

    define([ "screens/TitleScreen", "screens/GameScreen" ], function(titleScreen, gameScreen) {
    return {

        screenFuncs: {
            "TitleScreen" : titleScreen.TitleScreen,
            "GameScreen" : gameScreen.GameScreen,
        },

        buildScreen: function(data) {
            var func = screenFuncs[data.type];
            var screen = new func(data.params);
            return screen;
        },
    };
});

Do the paths in the define call need to be relative to the current location of the js file I'm in, or to the root defined in the app.js, anyway?

replace this:

define(["./screens/Screens"], function(screens) {
    ....
});

either with an absolut path variant:

define(["screens/Screens"], function(screens) {
    ....
});

or use:

define(function(require) {
    var screens = require("./screens/Screens");
    ....
});

From the docs:

Relative module names inside define():

For require("./relative/name") calls that can happen inside a define() function call, be sure to ask for "require" as a dependency, so that the relative name is resolved correctly:

define(["require", "./relative/name"], function(require) {
    var mod = require("./relative/name");
});

Or better yet, use the shortened syntax that is available for use with translating CommonJS modules:

define(function(require) {
    var mod = require("./relative/name");
});
