我尝试按照手册中概述的细节来配置箭头的外观。但是，我只得到错误。
我正在尝试从第 16.3 节中获取示例方向键工作。这是我的最小工作示例：
\documentclass{article}
\usepackage{pgf}
\usepackage{tikz}
\usetikzlibrary{arrows}
\usetikzlibrary{calc}
\listfiles
\begin{document}
\tikz{\draw[-{Stealth[length=5mm]}] (0,0) -- (2,0);}
\end{document}
这将产生以下错误：
! Package pgf Error: Unknown arrow tip kind 'Stealth'.
See the pgf package documentation for explanation.
Type H <return> for immediate help.
...
l.9 \tikz{\draw[-{Stealth[length=5mm]}]
(0,0) -- (2,0);}
?
如果我没有加载正确的库，我不确定它们应该是什么。
如果我尝试
\documentclass{article}
\usepackage{pgf}
\usepackage{tikz}
\usetikzlibrary{arrows}
\usetikzlibrary{calc}
\listfiles
\begin{document}
\tikz{\draw[-{stealth[length=5mm]}] (0,0) -- (2,0);}
\end{document}
笔记 stealth这次（而不是Stealth）。我收到错误：
! Package pgfkeys Error: I do not know the key 'length', to which you passed '5
mm', and I am going to ignore it. Perhaps you misspelled it.
See the pgfkeys package documentation for explanation.
Type H <return> for immediate help.
...
l.9 \tikz{\draw[-{stealth[length=5mm]}]
(0,0) -- (2,0);}
?
我做错了什么？
附言：我正在使用 2013 年 9 月 30 日的 TikZ CVS 版本：

该arrows库已贬值。请使用该库arrows.meta。
