I think you have cloned the master branch of the director, so your
module.info file contains
Version: master. Downloading the latest version will help.
Just a follow up:
download the latest release which at the time writing is 1.9.1.
Try the vspheredb module:
it has director import functionality but does not require director to work
in case it is intended to use the director master (not recommended):
patch modules info of vsphere and remove the depends part:
patch modules info of director and set version to idk 220.127.116.11 (not recommended):
