当我尝试在 Overlef 中编译下面的代码时,如果我设置LuaLaTeX
为 ,则会出现错误LaTeX Engine
,但如果我设置为 ,则不会出现错误Choose Automatically
。
\documentclass[a4paper,10pt]{book}
\usepackage{pst-electricfield,multido} % campos elétricos
\begin{document}
\begin{pspicture*}(-6,-6)(6,6)
\psframe*[linecolor=lightgray!50](-6,-6)(6,6)
\psgrid[subgriddiv=0,gridcolor=gray,griddots=10]
\psElectricfield[Q={[-1 -2 2][1 2 2][-1 2 -2][1 -2 -2]},linecolor=red]
\psEquipotential[Q={[-1 -2 2][1 2 2][-1 2 -2][1 -2 -2]},linecolor=blue](-6.1,-6.1)(6.1,6.1)
\psEquipotential[Q={[-1 -2 2][1 2 2][-1 2 -2][1 -2 -2]}, linecolor=green, linewidth=2\pslinewidth, Vmax=0, Vmin=0](-6.1,-6.1)(6.1,6.1)
\end{pspicture*}
\end{document}
这是我收到的错误:
./main.tex:8: Undefined control sequence.
<recently read> \c@lor@to@ps
l.8 \psframe*[linecolor=lightgray!50](-6,-6)(6,6)
Here is how much of LuaTeX's memory you used: 8148 strings out of 494688 ...
答案1
运行lualatex --shell-escape <file>
:
\documentclass[a4paper,10pt]{book}
\usepackage{auto-pst-pdf}
\ifpdf\else
\usepackage{pst-electricfield}
