Issues with ESXi 6.5

Excellent plugin but can’t get it working with ESXi 6.5

Version check_esxi_hardware.py 20111003 gives this error:

CRITICAL: (0, “Socket error: (1, ‘error:14077410:SSL routines:SSL23_GET_SERVER_HELLO:sslv3 alert handshake failure’)”)

Upgraded to version 20170905 but now get:
pkg_resources.DistributionNotFound: pywbem

How to upgrade pywbem since I get errors trying to install – wrong version of python maybe?

# python -V
Python 2.4.3
