The request lib was relying on a module called node-uuid. For some reason the author decided it was necessary to deprecate this module and continue with a module called uuid. Using node-uuid now spits warnings to users.
request fixed this in version 2.79.x, however because you chose to lock minor versions the many thousands of users that download this package each month have been getting warnings at build / install time.
Please bump the minor version or unlock the minor version. Thank you!
