gulp not running on Docker ubuntu - node.js

Question

I'm trying to use gulp to start a webpack compiler in a docker environment. Wheneever I try to run the command (in ssh, the Dockerfile, or the Procfile) it fails with error code 1 and prints nothing.
I checked and gulp is installed in node_packages, but when I run it from node_packages/.bin I get the same response. Running "npm" works, but running "node" appears not to work either.
Does anyone know what is going wrong?
Dockerfile
FROM quay.io/aptible/ubuntu:14.04
# Basic dependencies
RUN apt-install build-essential python-dev python-setuptools
RUN apt-install libxml2-dev libxslt1-dev python-dev

# RUN apt-install libpq-dev postgresql-client-9.3 postgresql-contrib-9.3
# MySQL dev headers (uncomment if you use MySQL)

RUN easy_install pip
RUN apt-install node
RUN apt-install npm
# Add requirements.txt and package.json ONLY, then run pip install, so that Docker cache won't
# bust when changes are made to other repo files
ADD requirements.txt /app/
ADD package.json /app/

RUN pip install -r requirements.txt
RUN npm install
# Add repo contents to image
ADD . /app/

Change these lines
RUN apt-install build-essential python-dev python-setuptools
...
RUN apt-install node
RUN apt-install npm
to these:
RUN apt-install build-essential curl python-dev python-setuptools
...
RUN curl -sL https://deb.nodesource.com/setup_4.x | sudo -E bash -
RUN apt-get install -y nodejs
You'll note we added curl to your tool installation and we're grabbing the node ppa, then installing it. This is going to give you the more current version of node on that branch. It will also come with npm, you do not need to install that separately.
Uncomment this line, as you want gulp to be a global install
# RUN npm install -g gulp
Correspondingly, in your proc file - use the global gulp
