Starting from VMware PowerCLI 13.0, Python 3.7.1 or later is a prerequisite for using the VMware.ImageBuilder module.
To use the VMware.ImageBuilder module, you must install Python 3.7.1 or later with four additional software packages and configure PowerCLI.
You must install the following additional packages in Python:
six
psutil
lxml
pyopenssl
You must configure PowerCLI by setting the path to your Python installation.
Restart your PowerShell session if you tried to execute a cmdlet from the VMware.ImageBuilder module before setting the path to the Python executable.
