Sorry :( There's been a problem (code: START_KARMA)
There was an error while starting karma server. Check you have the path to karma executable configured correctly and that karma config file is in the root of the current project.

This is my karma.conf.js ..
module.exports = function (config) {
'use strict';

config.set({

    // base path that will be used to resolve all patterns (eg. files, exclude)
    basePath: '',


    // frameworks to use
