TypeError: Cannot read property 'options' of undefined about karma-typescript

Thanks for the quick resolution! Adding karma-typescript to the frameworks array did the trick.

What does your config look like? Could you post that aswell?
And how do you import it?

Well, that was one unhelpful error message if I ever saw one... Turns out karma-typescript is missing in the Karma config frameworks array:

frameworks: ['mocha', 'chai', 'karma-typescript'],

I've added a framework check and a (hopefully) more helpful error message!

This looks like a windows paths issue, I'll try to reproduce the error!
