javascript - Trouble combining Require.js and Backbone.js/Underscore.js

Question

I've read previous threads where other members have had identical error messages as me, but their accepted solution doesn't seem to help.

Basically I get this in Chrome console when I try to load index.html:

Uncaught Error: Module name "underscore" has not been loaded yet for context: _. Use require([])

A couple of seconds later this shows up:

Uncaught Error: Load timeout for modules: underscore,backbone

Chrome network tools doesn't show any anomalies everything up until day_view.js is loaded fine (200 OK).

File structure

index.html

...
<script>
        var require = {
            deps: ["jquery/jquery-min", "underscore/underscore-min", "backbone/backbone-min"]
        };
</script>
<script data-main="scripts/main" src="scripts/require.js"></script>
...

main.js

require.config({
    baseUrl: 'scripts',

    paths:{
        jquery:'jquery/jquery-min',
        underscore:'underscore/underscore-min',
        backbone:'backbone/backbone-min'
    },

    shim: {
        underscore: {
            exports: '_'
        },
        backbone: {
            deps: ["underscore/underscore-min", "jquery/jquery-min"],
            exports: "Backbone"
        }
    },

    waitSeconds: 200
});

require(['day_view'], function (day_view) {
    function start() {
        day_view.render();
    }

    return {
        start:start
    };
});

day_view.js

define(['jquery', 'underscore', 'backbone'], function($, _, Backbone) {
    function render() {
        ...
    }
...

This finally worked.

require.config({
    paths:{
        jquery:'jquery/jquery-min',
        underscore:'underscore/underscore-min',
        backbone:'backbone/backbone-min'
    },
    shim: {
        underscore: {
            exports: '_'
        },
        backbone: {
            deps: ["underscore", "jquery"],
            exports: "Backbone"
        },
        waitSeconds: 15
    }
});

require(['day_view'], function (day_view) {
    function start() {
        day_view.show();
    }
    console.log(day_view); // Empty object here?
    return {
        start:start
    };
});

and

define(['jquery', 'underscore', 'backbone'], function($, _, Backbone) { ...
