问题安装VTK

Question

下载最新版本的VTK的（7.0.0）从vtk.org的tar.gz文件后，我做了一个build文件夹，运行ccmake，标志设置为Python3.5，设置标志PYTHON_WRAPPING打开并运行make，然后进行make install。然后，我做了一个

>>> import vtk 

我得到了以下错误：

In [1]: import vtk 
--------------------------------------------------------------------------- 
ImportError        Traceback (most recent call last) 
/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages/vtk/vtkCommonCore.py in <module>() 
     4  # use relative import for installed modules 
----> 5  from .vtkCommonCorePython import * 
     6 except ImportError: 

ImportError: dlopen(/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages/vtk/vtkCommonCorePython.so, 2): Library not loaded: libvtkCommonCorePython35D-7.0.1.dylib 
    Referenced from: /Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages/vtk/vtkCommonCorePython.so 
    Reason: image not found 

During handling of the above exception, another exception occurred:

     8  # e.g. in lib directory or Release/Debug config directories 
----> 9  from vtkCommonCorePython import * 

ImportError: No module named 'vtkCommonCorePython' 

任何想法，这可能是为什么发生？

Answer 1

我张贴VTK的邮件列表和伯纳德·吉鲁的答复是在同一个工作。下面是它（OS X埃尔卡皮坦）：

1. 运行cmake使用下列选项：

   cmake -DCMAKE_BUILD_TYPE=Release \ 
   -DCMAKE_INSTALL_PREFIX=/usr/local/VTK-7.0.0 \ 
   -DVTK_WRAP_PYTHON=ON \ 
   -DVTK_PYTHON_VERSION=3 \ 
   -DCMAKE_MACOSX_RPATH=ON \ 
   -DCMAKE_INSTALL_NAME_DIR=/usr/local/VTK-7.0.0/lib .. 
   

2. 在/ usr /本地VTK -> VTK-7.0.0

3. 做一个符号链接在.bash_profile中添加

   export VTKPATH=/usr/local/VTK 
   export PYTHONPATH=$VTKPATH/lib/python3.5/site-packages 
   

   （或者任何python3.5/site-packages的路径; which python3.5都可以使用得到这个）

这对我有效。
