Problems running npm install on Elastic Beanstalck - node.js

Question

Situation
I have a Laravel (5.4) application that uses npm, bower and gulp for frontend.
I have configured all with success on deploy but the npm install or npm install --production (that in my case is the same) command give me errors and makes the deploy to fail.
Problem
Here is the "Causes" as response from AWS when i run eb deploy command.
Application update failed at 2017-06-07T17:08:38Z with exit status 1 and error: container_command 01-npm-install in .ebextensions/05-frontend-install.config failed.

Incorrect application version "app-5d9c-170607_190633" (deployment 40). Expected version "app-0466-170606_110037" (deployment 31).
The .ebextensions/05-frontend-install.config file has this content
container_commands:
00-npm-upgrade:
command: "npm install -g npm#latest"
01-npm-install:
command: "npm install --production"
02-gulp-install:
command: "sudo npm install gulp"
03-bower-install:
command: "sudo npm install bower"
04-bower-deploy:
command: "sudo bower install --allow-root"
05-gulp-deploy:
command: "sudo npm run prod"

Achived with an EB HOOK!
I solved my problem by using a custom elastic beanstalk post-deploy platform hook (sounds great eh?)
my 04-nodenpm.config file has this content:
container_commands:
00-entersudoi:
command: "sudo -i"
01-removeoldnode:
command: " yum remove -y nodejs npm"
02-get-noderpm:
command: " curl --silent --location https://rpm.nodesource.com/setup_7.x | bash -"
03-ensurecggmake:
command: " yum install -y gcc-c++ make"
04-installnodenpm:
command: " yum install -y nodejs"
05-exitsudoi:
command: "exit"
files:
"/opt/elasticbeanstalk/hooks/appdeploy/post/99npminstall.sh":
mode: "000755"
owner: root
group: root
content: |
#!/usr/bin/env bash
cd /var/app/current/
sudo npm install -g gulp bower laravel-elixir
sudo bower install --allow-root
sudo gulp --production
The part that solved the problem is under files: where i am manually adding an /opt/elasticbeanstalk/hooks/appdeploy/post/99npminstall.sh file with content: that as a post deploy action makes the npm install ... and all the stuff i wanted.
TL;DR:
npm seems not be totally available on container_commands. Use a post deploy hook to fire those npm installation commands.
