Why is the Travis CI build erroring?

I have been waiting for this fix for a long long time. Thank you for referencing the issue I would have never heard of it. I'll reply here if I see that stupid error again!

Why is the Travis CI build erroring?

@NoelDavies Good question... I will look into it.

[douglassllc]

It seems the travis-ci was failing because the package uses yarn, while I use npm which created a package-lock.json file that was conflicting with yarn.

Now the reason for the travis-ci failure seems to be because my credentials do not have permissions to the repo.

ERROR  Could not add github status.
        401: Bad credentials 

@MrEmelianenko @Stormtv @PaulBernier can one of you finalize this PR. Let's keep this package alive.
