如何安裝使用conda啟用gl2ps的vtk

Question

我正在使用anaconda，我用conda建立了vtk

conda install vtk

vtk的默認構建是沒有gl2ps ，我想知道如何使用conda啟用gl2ps來構建（或者更確切地說重建）vtk。

我實際上是想要解釋這個示例代碼：

 from mayavi import mlab
 mlab.test_plot3d()
 mlab.savefig(temp.eps)

但得到錯誤

Saving as a vector PS/EPS/PDF/TeX file using GL2PS is either not supported by your version of VTK or you have not configured VTK to work with GL2PS -- read the documentation for the vtkGL2PSExporter class.

謝謝

我下載了coda-recipes

git clone https://github.com/conda/conda-recipes.git

即使我不編輯文件以包含gl2ps

用於構建vtk的配方就在這里 。 您應該修改它以包含該包並使用conda build vtk/ 。
