Docker npm install fails - node.js

Question

I'm trying to build an ASP.Net 5.0 web app using Docker, but it fails when it reaches the npm install step, with:
Step 14 : RUN npm install

The command 'npm install' returned a non-zero code: 1
ERROR: Build failed with: exit status 1
I can't see any errors here that explain why it's failing, only WARNings. I assume this must either be a problem with the npm installation or the modules it's trying to install. loadash#1.0.2 says it will fail on newer npm installs, but I don't know how to update this, or which of the dependencies is pulling this in.

Not sure, but 1st: you can try install with sudo npm install, and 2nd you can try to install on this machine node-gyp and pyton 2.7 . If module during installation require compilation of node extension, then you will need these two things.
3rd. How we usually debug: Create an image on the state before failing command. run container with interactive shell (with -it). login inside. And run npm install by hands. See and understand output there. Fix.
