FAIL: Deploy MEAN.js app to Elastic Beanstalk - node.js

Question

I'm deploying my MEAN.js Node app to AWS. Steps 1-4 are the commands I run from my local machine:
1) grunt build (DONE)
2) git commit -m "production deployment" my newly concatenated production files. (DONE)
3) Set NODE_ENV=productionon AWS. (DONE)
3) Set the AWS "NodeCommand" to grunt. (DONE)
4) git aws.push (DONE)
At this point my deployment fails because the app is uploaded to my EC2 then grunt gets called but since grunt isn't install globally the app fails to start.
I've tried settings step 3 to node_modules/grunt-cli/bin/grunt
Here is my package.json (which should install bower dependencies when app starts.. I think).
