    Looks like in case if `npm` is not available this will return a promise rejection which
is never propagated to the caller. Probably you need to wrap this call and all the code below
into top-level promise (similar to #384). This would also protect the code against [CB-10519](https://issues.apache.org/jira/browse/CB-10519)
