ImportError: No module named vtkCommonPython

Question

I am trying to install Python with VTK on my computer, but when I want to import VTK, I get an error:

import vtk 
Traceback (most recent call last): 
 File          


        

Answer 1

Assuming you used the suggested paths in the instructions, add the following line to your bashrc:

export PYTHONPATH=$HOME/projects/VTK-build/lib:$HOME/projects/VTK-build/Wrapping/Python:$PYTHONPATH

If the problem occurs when using sudo, e.g.

sudo yum install mayavi

you probably need to resolve this issue. Add the following line to the bashrc:

alias sudo=’sudo env PYTHONPATH=$PYTHONPATH’

You need to add the folder of vtkCommonPython.pyd also to the system path (like if it was a dll). See also http://www.vtk.org/Wiki/VTK/Tutorials/PythonEnvironmentSetup
