examples.native() AND examples.with_vtk() fail

kayarre commented 5 years ago

running pymeshfix after install with pip first error:

import pymeshfix
from pymeshfix import examples
examples.native()

---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)

     13     """ Repair Stanford Bunny Mesh """
---> 14     pymeshfix._meshfix.CleanFromFile(bunny_scan, outfile)

AttributeError: module 'pymeshfix._meshfix' has no attribute 'CleanFromFile'

The second error happens with examples.with_vtk() after closing the window that pops up

examples.with_vtk()

I have run this now on linux and osx and get the same errors

print(pv.Report('pymeshfix'))
