npm WARN deprecated [email protected]: request has been deprecated, see https://github.com/request/request/issues/3142

Expected Behavior

No warnings are printed.

While this bug is specifically describing Node warnings about "Accessing non-existent property", it would be eventually nice to get rid of request dependency too.

It might be related to shelljs.

Running NODE_OPTIONS="--trace-warnings" lb4 confirms that shelljs is the root cause.

If you allow me, I will close this issue. With the maintenance of the package-lock's it has been fixed
