python - 如何使用 conda 启用 gl2ps 安装 vtk

Question

我正在使用 anaconda，我已经使用 conda 构建了 vtk

conda 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(或更确切地说是重建)vtk。

我实际上正在尝试执行这个示例代码:

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

但是报错

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

编辑

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

用于构建 vtk 的配方是 here .您应该修改它以包含该包并使用 conda build vtk/ 进行构建。
