使用 xelatex 进行 pstricks 和 beamer 编译导致 xkeyval 错误

Question

我正在制作一些幻灯片，需要包含 pstricks 图像。我想通过 编译该文件xelatex。

我最简单的例子如下

\documentclass[ngerman,xcolor=pst]{beamer}
\usepackage{fontspec,babel}
\usepackage{pst-solides3d,pst-3dplot,pst-eucl,pstricks}%
\title{Test}
\begin{document}
\begin{frame}
\begin{center}
\psset{unit=2}
\begin{pspicture}(-1.9,-0.7)(3,2.1)
\psset{viewpoint=3 -10  3,Decran=20,lightsrc=viewpoint}
\defFunction[algebraic]{sphere}(u,v){cos(u)*cos(v)} {sin(u)*cos(v)} {sin(v)}
\psSolid[object=surfaceparametree,base=pi neg pi 0 1,hue=0.3 0.3,function=sphere,linewidth=0.2pt,opacity=0.6,ngrid=0.1]
\axesIIID(1,3.5,.75)(1.25,5,1)
\psSolid[object=vecteur,args=0.707 -0.5 0.5,label=n](0.707,-0.5,0.5)
\psellipticarc{<-}(0,1.6)(1,0.2){300}{400}
\psellipticarc{->}(0,-0.1)(1.82,0.575){200}{340}
\end{pspicture}
\end{center}
\end{frame}
\end{document}

并导致错误

! Package xkeyval Error: `label' undefined in families `,pstricks,pst-node,pst-
solides3d,pst-3d,pst-plot,pst-3dplot,pst-eucl'.

See the xkeyval package documentation for explanation.
Type  H <return>  for immediate help.
 ...                                              

l.19 \end{frame}

完成方式如下xelatex --version：

我不知道该如何解决这个问题。谁能帮忙？
当然，我查看了 xkeyval 文档：解释The keyname is not defined in the families. Probably you mistyped name.没有帮助。
提前致谢。

Answer 1

\psSolid[object=vecteur,args=0.707 -0.5 0.5,label=n](0.707,-0.5,0.5)

有不 label关键字已定义。不知道你在哪里读到的。
