npm link package name must have a name field to be linked

Hi I am trying to create a docker image. Below is a part of my docker file which is causing problem.I think the problem is due to nodejs package.

The current softlink is: ls -la "/usr/bin/npm" lrwxrwxrwx 1 root root 25 Mar 2 01:50 /usr/bin/npm -> /usr/lib/node_modules/npm

Installation is does by a nonroot user

Docker File

 #Install node js and npm
    RUN curl -sL https://deb.nodesource.com/setup_6.x | sudo -E bash -
    RUN apt-get -y install nodejs
    RUN npm install -g bower gulp
    RUN npm install -g node-gyp@latest --save
    RUN npm init -y
    RUN npm install -g n
    RUN npm install zmq --save
    RUN ldconfig
    RUN npm config set prefix ~/npm

    #RUN npm install -g stf t
    #RUN npm install
    #RUN rm -rf /usr/bin/npm
    #RUN ln -s /usr/lib/node_modules/npm/ /usr/bin/npm
    RUN npm link

Below is the docker build output:

The problem is that the generated package.json does not have the name property set "name": "",.

As documented in npm-link:

Note that package-name is taken from package.json, not from directory name

The reason why name is empty in package.json is that you are running npm init in the root / of the container. You have to create a directory and run npm init in there.

...
WORKDIR /app
RUN npm init -y
...
