问题:

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. But I have not used it for this installation.

I've manually installed all it's dependencies, including VTK.

For VTK, I followed its installation guide and installed the python wrapper.

Now if I open a new terminal window and open python, I can import vtk without any error.

Problem

I try to install Mayavi with the following command:

pip install mayavi

But the following error occurs:

I think the problem is with vtk.

Can anyone help me?

Other Details

Running sudo pip install mayavi does not solve the problem.

I thought this might help

My PYTHONPATH is empty.

回答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

For more installation instructions, see http://www.pip-installer.org/en/latest/installing.html

回答2:

I'm on Debian but this should work for you as well

I was stuck with installing vtk into a virtualenv, after hours of search with no results I did the following and it worked.

install python-vtk from repositories systemwide
copy vtk folder from /usr/lib/pymodules/python2.7 to /PATH/TO/YOUR/VIRTUALENV/lib/python2.7/site-packages

In your case the system-wide python packages folder would probably be different but you can easily find it by firing up system python and entering the following:

import vtk,sys print(sys.modules['vtk'])

After this trick mayavi was succesfully installed into my virtualenv using pip install mayavi and pip install envisage.

Edit: instead of copying it might better to just symlink the folder in step 2

回答3:

I had the same problem and the first answer didn't help me because pip was in the right directory, but it turned out I didn't have vtk installed - running sudo apt-get install python-vtk fixed the issue and I was able to successfully run pip install mayavi after that.

回答4:

I had the same problem when installing mayavi with python installed in pyenv, and I solved this problem by copy directory to /home/myname/.pyenv/versions/2.7.12/lib/python2.7/site-packages, below is my method:

install vtk and python-vtk

sudo apt-get install vtk6 sudo apt-get install python-vtk

try python -c "import vtk", if failed again, go to step 3
the import error may caused by the loss of vtk package folder in your current python, so we should find the vtk folder and copy to your current python(most possible the python in pyenv shims directory)'s directory .

the path of the vtk folder in my ubuntu is
```
/usr/lib/python2.7/dist-packages/vtk
```
just copy the vtk folder to your current python's /site-packages, e.g.
```
cp -r /usr/lib/python2.7/dist-packages/vtk /home/myname/pyenv/versions/2.7.12/lib/python2.7/site-packages
```
try python -c "import vtk" again.
if no import error, just do
```
pip install mayavi
```
