installing Mayavi with pip - no module named vtk

Question

I want to use Mayavi.

Situation

• I use a MacBook Air, with OSX 10.7.3.
• I use Python 2.7.2
• I have virtualenv installed.

Answer 1

Your pip is probably using a different python, kind of you have vtk installed using /usr/local/bin/python, while your pip binary uses /usr/bin/python.

Check it:

$ head -n1 $(which pip)

In order to get it solved, you can choose to use a virtualenv, or install pip using /usr/local/bin/python:

curl https://raw.github.com/pypa/pip/master/contrib/get-pip.py | /usr/local/bin/python
