Error Deploying React App on Heroku...

I set up my React app and now I am ready to deploy. I've followed the steps provided to simply host on Heroku but, I'm hitting errors when I git push heroku master.

Here's my terminal printout:

Did you remember to use --save when you installed react-router so it would be added to your package.json file?

Thank you, I was missing that as a dependency.
