AWS EB deployment issue

I'm trying to deploy a Node.js app to Elastic Beanstalk. The app is locally working properly. However, when I try to deploy, I get the error:

Failed to run npm install. Snapshot logs for more details. 

Here is a screenshot of the EB log for more detail:

Error Log (I found it interesting that I got permission denied - what could that mean?):

Package.json:

{ "name": "MyProject", "version": "0.0.1", "private": true, "dependencies": { "body-parser": "latest", "express": "latest", "node": "latest", "nodemailer": "latest" }, "scripts": { "start": "node app.js" } } 

Why does this happen?

EDIT: Added package.json and error log as requested.
