Having this in your config should work:
paths: {
underscore: <path to lodash>,
backbone: <path to backbone>,
jquery: <path to jquery>
}
You must use a version of lodash that is compatible with Backbone. This is the one created with lodash backbone
when you use the CLI. You do not need shims of any of these. Defining underscore
so that it points to lodash will make Backbone use lodash.
