Webpack dependency error 
While trying to run `npm install -D webpack-cli`, I got the following error:

    npm WARN old lockfile 
    npm WARN old lockfile The package-lock.json file was created with an old version of npm,
    npm WARN old lockfile so supplemental metadata must be fetched from the registry.
