我正在使用anaconda，并且我已经使用
使用conda构建了vtkconda install vtk
vtk的默认构建没有gl2ps，我想知道如何使用conda启用gl2ps来构建（或者更确切地说重建）vtk。
我实际上是想要解释这个示例代码：
from mayavi import mlab
mlab.test_plot3d()
mlab.savefig(temp.eps)
但得到错误
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.
谢谢
修改
我下载了coda-recipes
git clone https://github.com/conda/conda-recipes.git
即使我不编辑文件以包含gl2ps
