Unable to npm install private npm module using ciricleci 2.0

Build Environment
1

I have this step defined in my test job in circleci 2.0

  tests:
    docker:
      - image: buildpack-deps:trusty
    steps:
      - checkout
      - run:
          name: npm secret
          command: echo "//registry.npmjs.org/:_authToken=${NPM_TOKEN}" > ~/.npmrc

I have ssh’d to the container and verified that the .npmrc is properly created.

However, npm install still fails with

npm ERR! 404 'myprivatemodule' is not in the npm registry.
npm ERR! 404 You should bug the author to publish it
npm ERR! 404

npm works without issue in circleci 1.0

Any way to resolve this issue?
