I have the same issue as described here: Using Angular Dragula without RequireJS
It works if do this:
var app = angular.module('app', [
angularDragula(angular)
]);
<script src="node_modules/angularjs-dragula/dist/angularjs-dragula.js"></script>
But all the jasmine tests fail with: Error: ReferenceError: Can't find variable: angularDragula
Check your configuration file. You should have an array of file paths which includes angularjs-dragula.js, and the files must be ordered correctly (dependencies must come before the files that depend on them).
