This is a common error caused by a broken Python installation or
attempting to mix Python versions (e.g. setting PYTHONPATH or
PYTHONHOME to point to one version but using the Python interpreter
from a different version).

With respect to GRASS, the usual reason for this error is the attempt
to "bundle" a copy of Python in the GRASS installer.

Bear in mind that, on Windows, "executing" a Python script (whether
from cmd.exe, the GUI, or via subprocess.Popen() or os.system()) will
use the Python interpreter associated with the .py extension. If
PYTHONHOME and/or PYTHONPATH refer to a different version, it will
break.
