That's a different error message than you reported at first.  If you
can't even run an example supplied with the system, you'd better post a
question on the vpython forum (I presume it's available from
http://vpython.wikidot.com/system:join)   Presumably the install program
is broken.  Or maybe you just can't run visual from IDLE.  Try running
from the terminal prompt.

I'm amazed that it uses   the form:    from visual_all import *
That's considered bad form.  Still, it's probably not the problem.  What
happens if you write a two line program:
    import visual_all
    print("Import succeeded")
