我想用 tikz 包绘制一个非常简单的 $\LaTeX$ 图表，但是它给出了一个错误，如下所示：
来源：

\begin{document}
\begin{tikzcd}

\end{tikzcd}
\end{document}

l.12 I think the culprit is a tikzcd arrow in cell 1-1.

答案1
你命令箭头向下，但什么也没有
\documentclass{article}
\usepackage{amssymb} \usepackage[utf8]{inputenc} \usepackage{tikz-cd}
\begin{document}
\begin{tikzcd} A\arrow[d,tail,two heads,dashed] & B
\\ c& \end{tikzcd}
\end{document}
答案2
如果您确实需要目标单元格中没有任何内容的向下箭头，则可以使用nodes in empty cells选项：
\documentclass{article}
\usepackage{amssymb}
\usepackage[czech]{babel}
%\usepackage[utf8]{inputenc} no more needed
\usepackage{tikz-cd}
\begin{document}
\begin{tikzcd}[every matrix/.append style={nodes in empty cells}]
A\arrow[d,tail,two heads,dashed] & B\\
&
\end{tikzcd}
\end{document}
