[Visualpython-users] Mac installation question.

[Gary P. <gar...@gm...>]

Our IT dept. just installed vpython on the 'clean' Macs in our lab.  AFAIK,
they followed the instructions on vpython.org.

Unfortunately, python can't find packages.  numpy and visual are installed
in the "Frameworks" site-packages directory, but they are not found on
import.

One problem is that PATH is not set properly.  which python ==>
/usr/bin/python

But if I launch python using the entire path to the executable, then import
numpy, I get the attached traceback.

Anyone know what the missing link is?

thanks,
gary
