我正在尝试使用 pst-dbicons 包 (PSTricks) 创建 ER 图。但是，在尝试示例 tex 文件时，我在第 55 行收到错误：“未定义控制序列”。我将示例粘贴在此处：

知道原因吗？
答案1
latex->dvips->ps2pdf使用和运行示例不是 pdflatex或使用
...
\usepackage{auto-pst-pdf}
...
...
\begin{postscript}
% lang/rel/ethn
\begin{tabular}{c}
...
\end{postscript}
\attributeof{Desert}{0}{area}
}
\end{postscript}
...
然后使用pdflatex --shell-escape
