Node.js Question

Bcrypt: invalid ELF header with Docker and Sails.JS

My Node

Dockfile
:

# Set the base image to ubuntu
FROM ubuntu

# Define working directory
ADD . /src
WORKDIR /src

# Install Node.js & other dependencies
RUN apt-get update && \
apt-get -y install curl && \
apt-get -y install sudo && \
curl -sL https://deb.nodesource.com/setup_0.12 | sudo bash - && \
apt-get -y install python build-essential nodejs

RUN npm install -g node-gyp && \
node-gyp clean && \
npm cache clean

RUN node -v

# Install nodemon
RUN npm install -g nodemon


ADD package.json /src/package.json
RUN cd /src && npm install


# Expose port
EXPOSE 8080

# Run app using nodemon
CMD npm install; nodemon /src/app.js


Here is my
docker-compose.yml
:

nginx:
build: ./nginx
links:
- node1:node1
- node2:node2
- node3:node3
ports:
- "80:80"
redis:
image: redis
ports:
- "6379"
node1:
build: ./node
links:
- redis
ports:
- "8080"
node2:
build: ./node
links:
- redis
ports:
- "8080"
node3:
build: ./node
links:
- redis
ports:
- "8080"


docker-compose build
runs successfully and Redis/Nginx setup correcly on
docker-compose up
but the node instances throw this error:

I've searched all over and can't seem to find a solution that works. I've tried using the regular setup url:
https://deb.nodesource.com/setup
, specifically installing
python2.7
, and using the
ubuntu:15.04
image.

I've read that this happens when people try to use bcrypt on a linux env after it was built on a OS X (my OS), but I don't think that would be the issue since I'm building everything using docker and boot2docker.

Answer

In my package config I had "bcrypt":"^0.8.0" and when I took out the ^ and changed it to "bcrypt":"0.8.0" I was able to get everything running.

The issue was that it was trying to run bcrypt 0.8.5 and that was causing issues for some reason.
