我正在尝试通过运行来执行 dot2texi 手册中的以下示例pdflatex --shell-escape pres.tex：
\documentclass{article}
\usepackage{dot2texi}
\usepackage{tikz}
\usetikzlibrary{shapes,arrows}
\begin{document}
\begin{dot2tex}[neato,mathmode]
digraph G {
node [shape="circle"];
a_1 -> a_2 -> a_3 -> a_4 -> a_1;
}
\end{dot2tex}
\end{document}
此操作失败并显示以下错误消息：
This is pdfTeX, Version 3.14159265-2.6-1.40.17 (TeX Live 2016) (preloaded format=pdflatex)
\write18 enabled.

如果我运行不带它的命令，--shell-escape它会给我同样的错误，只不过它还告诉我应该使用--shell-escape。我已经检查过，我有以下可用：
- xkeyval latex 包
- moreverb latex 包
- pgf latex 包装
- pstricks 乳胶包装
- graphviz 包
- dot2tex 包
知道我能做什么吗？
