Python 3.x is not guaranteed to be backwards compatible with Python 2.x, and I don't think Lilypond has been ported to Python 3. So you probably do need to be running the earlier Python version with lilypond-book. Why it should give an error after you changed the PATH back to what it was before, I don't know... :-( _______________________________________________ lilypond-user mailing list lilypond-user@gnu.org http://lists.gnu.org/mailman/listinfo/lilypond-user
