npm install -g @shoutem/cli yields "deprecated [email protected]: ⚠️ WARNING ⚠️ tar.gz"

I'm on OSX 10.14.2. After running npm install -g @shoutem/cli I get the following errors:

npm WARN deprecated [email protected]: Potential security vulnerability fixed in v.1.2.4
npm WARN deprecated [email protected]: ⚠️ WARNING ⚠️ tar.gz module has been deprecated and your application is vulnerable. Please use tar module instead: https://npmjs.com/tar
npm WARN deprecated [email protected]: CircularJSON is in maintenance only, flatted is its successor.
npm WARN deprecated [email protected]: to-iso-string has been deprecated, use @segment/to-iso-string instead.
npm WARN deprecated [email protected]: Jade has been renamed to pug, please install the latest version of pug instead of jade
npm WARN deprecated [email protected]: Please update to minimatch 3.0.2 or higher to avoid a RegExp DoS issue

Any idea how I can fix this? Especially the tar.gz. So far I've tried updating node to the latest stable version.
