我正在尝试使用latexmk。asymptote我在当前目录中有一个名为 的文件latextest.tex和一个名为 的文件夹build。 的内容latextest.tex如下：
\documentclass{article}
\usepackage{asymptote}
\def\asydir{build}
\begin{document}
Hello World.
\begin{asy}
size(7cm);
pair A = dir(120);
pair B = dir(210);
pair C = dir(330);
draw(A--B--C--cycle, red + 1.2);
\end{asy}
\end{document}
当我通过运行以下命令编译此文件时，
pdflatex latextest.tex
asy -o build/ build/latextest-1.asy
pdflatex latextest.tex
它可以毫无问题地编译。
但是，当我运行时latexmk latextest.tex，它会产生以下错误消息。

我的.latexmkrc文件如下：
sub run_asy {return system("asy -o build/ '$_'");}
add_cus_dep("asy", "eps", 0, "run_asy");
add_cus_dep("asy", "pdf", 0, "run_asy");
add_cus_dep("asy", "tex", 0, "run_asy");
.asy执行从到 的转换子程序时似乎出现了问题.eps。这里可能出了什么问题？
答案1
在定义自定义依赖项时，$_应将 替换为$_[0]，以便.latexmkrc包含：
sub run_asy {return system("asy -o build/ '$_[0]'");}
add_cus_dep("asy", "eps", 0, "run_asy");
add_cus_dep("asy", "pdf", 0, "run_asy");
add_cus_dep("asy", "tex", 0, "run_asy");
