Cannot Find Module 'express' With Node.js Using Docker

hason21

I'm a newbie with Docker and I'm trying to start with NodeJS hosted in asphostportal.com so here is my question..

I have this Dockerfile inside my project:

FROM node:argon

# Create app directory
RUN mkdir -p /home/Documents/node-app
WORKDIR /home/Documents/node-app

# Install app dependencies
COPY package.json /home/Documents/node-app
RUN npm install

# Bundle app source
COPY . /home/Documents/node-app

EXPOSE 8080
CMD ["npm", "start"]

When I run a container with

docker run -d -p 49160:8080 node-container

it works fine..
But when I try to map my host project with the container directory (

docker run -p 49160:8080 -v ~/Documentos/nodeApp:/home/Documents/node-app node-cont

) it doesn't work.
The error I get is:

Code:

Error: Cannot find module 'express'

I've tried with other solutions from related questions but nothing seems to work for me (or I know.. I'm just too rookie with this)
Thank you !!

You need to install the express package with NPM.

BTW the mods can move this to Development, its more suited to programming/dev questions than C&T (which is mostly "My laptop is slow help xx").
