我正在尝试绘制如下所示的曲线：
%&lualatex
% !TeX program = lualatex
\documentclass[border=5pt]{standalone}
\usepackage{pgfplots}
\pgfplotsset{compat=newest}
\begin{document}
\begin{tikzpicture}
\begin{axis}
\addplot [red] {-sqrt(x^3+7)};
\end{axis}
\end{tikzpicture}
\end{document}
问题是，该解决方案在 中运行得很好pdflatex，但是，当我尝试使用 编译这个MWE（在答案中给出）时lualatex，我收到一系列错误，例如：
