You must add paths in requirejs.config to declare, example:

requirejs.config({
    paths: {
          'underscore' : '.../example/XX.js' // your JavaScript file
          'jquery' : '.../example/jquery.js' // your JavaScript file
    }
    shim: {
        'backbone': {
            deps: ['underscore', 'jquery'],
            exports: 'Backbone'
        },
        'underscore': {
            exports: '_'
        },
        'foo': {
            deps: ['bar'],
            exports: 'Foo',
            init: function (bar) {
                return this.Foo.noConflict();
            }
        }
    }
});
