I had the same problem and rather than spend too long looking it to it I just used the same versions of plug-ins as John. I know this doesn't solve the problem; I just wanted to complete the course and then come back to this at a later point

First of all i see that you are using version above 0.13. So lets fix the start method that was deprecated in 0.13.

var Server = require('karma').Server;
var server = new Server({
        configFile: __dirname + '/karma.conf.js',
        exclude: excludeFiles,
        singleRun: !!singleRun
    }, karmaCompleted);

Now let's fix the second error, We can see that we have two problems:

1. Gulp complaining about a format error due to the arguments passed to the callback function done.

2. karma keeps running even after the test are done.

here the code of functionCompleted by @johnpapa:

function karmaCompleted(karmaResult) {
        log('Karma completed!');
        if (karmaResult === 1) {
            done('karma: tests failed with code ', karmaResult);
        } else {
            done();
        }
    }

And below is the quick fix, i created a variable status that with display either 'ERROR' or 'SUCCESS' depending on karma's exitCode that will be passed by karma to our karmaCompleted function in the form of karmaResult variable, then stripped the arguments passed to done() and lastly added the process.exit(karmaResult) in order to end karma once the tests finish.

 function karmaCompleted(karmaResult) {
        var status = karmaResult === 1 ? 'ERROR' : 'SUCCESS';
        log('Karma completed with: ' + status);
        log('Exit Code: ' + karmaResult);
        done(); // stripped the arguments that gulp complains about
        process.exit(karmaResult); // tell karma to exit once tests are done

    }

And voila, i hope this helps!
