下面的代码使用 Ti钾Z 库calligraphy，但抛出一个错误：
Package pgfkeys Error: I do not know the key '/pgf/decoration/\pgfkeyscurrentname ' and I am going to ignore it. Perhaps you misspelled it.
常规 Ti钾Z 支架按预期工作。
可能缺少了一些基本的东西，但到目前为止我还没有找到解决方案。
更新：使用 MacTeX 2019，已更新。
\documentclass{article}
\usepackage{tikz}
\newsavebox{\barbox}
\usetikzlibrary{calligraphy,decorations.pathreplacing}
\begin{document}
\begin{lrbox}{\barbox}
\begin{tabular}{lll}
1&2&3\\
A&B&C\\
X&Y&Z
\end{tabular}
\end{lrbox}
\tikz{%
\node (z) {\usebox{\barbox}};
%% This works:
%\draw[decorate,decoration={brace,mirror}]
%% This gives error:
%% Package pgfkeys Error: I do not know the key '/pgf/decoration/\pgfkeyscurrentname ' and I am
%% going to ignore it. Perhaps you misspelled it.
\draw[decorate,decoration={calligraphic brace,amplitude=2mm,mirror}]
(z.south east) -- (z.north east);
}
\end{document}
答案1
这书法手册第 7 页上说：
如果在此库之前加载了 TikZ/PGF 装饰库，则书法库会定义一些使用书法路径的装饰，特别是使用铜版笔尖。当前的装饰是：• 书法括号换括号。[...]
因此：先加载decorations.pathreplacing，然后加载calligraphy。
梅威瑟：
\documentclass{article}
\usepackage{tikz}
\newsavebox{\barbox}
\usetikzlibrary{decorations.pathreplacing,calligraphy}
\begin{document}
\begin{lrbox}{\barbox}
\begin{tabular}{lll}
1&2&3\\
A&B&C\\
X&Y&Z
\end{tabular}
\end{lrbox}
\tikz{%
\node (z) {\usebox{\barbox}};
\draw[decorate,decoration={calligraphic brace,amplitude=2mm,mirror}]
(z.south east) -- (z.north east);
}
\end{document}
结果：
