Cannot read property 'deep' of undefined

See original GitHub issue

With webpack, doing :

npm install jointjs require("jointjs")

it gives the following error :

Cannot read property 'deep' of undefined

Here is the full stacktrace :

The part of the corresponding code in joint.js is :

        mixin: function() {

            var target = arguments[0];

            for (var i = 1, l = arguments.length; i < l; i++) {

                var extension = arguments[i];

                // Only functions and objects can be mixined.

                if ((Object(extension) !== extension) &&
                    !_.isFunction(extension) &&
                    (extension === null || extension === undefined)) {

                    continue;
                }

                _.each(extension, function(copy, key) {

                    if (this.mixin.deep && (Object(copy) === copy)) {

                        if (!target[key]) {

                            target[key] = _.isArray(copy) ? [] : {};
                        }

                        this.mixin(target[key], copy);
                        return;
                    }

Any idea ?

Had the same problem. Its probably a Lodash version problem, I just switched from 4.13.1 to 3.10.1 and it worked.

We have also been stuck using 3.10 because of this dependency. It would be great to remove it or bundle it so there’s not version conflicts like this. IMO, there should probably be a new issue created to do one or the other so people interested can follow what is happening regarding it.

Or would you guys be open to a pull request updating everything to lodash 4.x?
