How to run `npm install` in Amazon Elastic Beanstalk with .ebextensions

Question

I want to deploy my PHP app in a Amazon Elastic Beanstalk with eb deploy command. But my app use gulp to concat and minify scss and js.

So I tried these commands to in the file .ebextensios/03npm.config

commands:
  01-install-node:
    command: "yum install nodejs npm --enablerepo=epel -y"

container_commands:
  01-install-dependencies:
    command: "npm install"
  02-build:
    command: "npm run build"

But in the end I receive this error

[Instance: i-c7800103] Command failed on instance. Return code: 1 Output: (TRUNCATED)...ttps://registry.npmjs.org/acorn npm http 304 https://registry.npmjs.org/amdefine npm http 304 https://registry.npmjs.org/wrappy npm ERR! npm ERR! Additional logging details can be found in: npm ERR! /var/app/ondeck/npm-debug.log npm ERR! not ok code 0. container_command 01-install-dependencies in .ebextensions/03npm.config failed. For more detail, check /var/log/eb-activity.log using console or EB CLI.

I'm not sure but it appears that npm install receive an error from one package that could be ignored but it is dispatching the EB error and stopping the whole process.

I'm running with this machine: 64bit Amazon Linux 2015.09 v2.0.4 running PHP 5.6

Does anyone know how we can fix this?

Until now, I have this ugly solution, but it works. I created this script inside package.json that do the hard job in sequence. It create a new branch and commit the compiled files before deploy it to EB

package.json

{
  "scripts": {
    "production": "node ./node_modules/gulp/bin/gulp.js --production",
    "deploy": "git checkout -b deploy && npm run production && git add . && git commit -m \"build\" && eb deploy && git checkout master && git branch -D deploy"
  }
}

.elasticbeanstalk/config.yml

branch-defaults:
  deploy:
    environment: NAME_OF_ENVIRONMENT
