title: Ignore local .npmrc config file during npm install
body: <p>How do I ignore a local .npmrc config file while running <code>npm install</code>?</p>
  <p>Is there a command like <code>npm install --ignore-local-rc</code> or something similar? I feel this can be useful for situations where you want to pull packages from the public npm registry by-passing the private registries specified.</p>
