为了使用隐形形状的箭头,我在序言中添加了这一点
\usetikzlibrary{shapes,arrows,chains,positioning,calc}
\usetikzlibrary{arrows.meta}
编译的时候,控制台卡住
(C:\MiKTex\tex\generic\pgf\frontendlayer\tikz\libraries\tikzlibraryautomata.code.tex)
,没有错误信息。
梅威瑟:
\documentclass[11pt]{article}
\usepackage{tikz}
\usetikzlibrary{shapes,arrows,chains,positioning,calc}
\usetikzlibrary{arrows.meta}
\begin{document}
\begin{tikzpicture}[scale=8]\centering
\usetikzlibrary{automata,positioning}
\tikzset{
%Define standard arrow tip

%Define style for boxes
punkt/.style={

% Define arrow style

}
\node [punkt, draw = blue] at (0,0) {$x>y$};
\node [punkt, draw = red] at (0.8, 0) {$x<y$};
%
\node[] at (0.15, 0.03) (0up) {};
\node[] at (0.65, 0.03) (1up) {};
\path (0up) edge[pil, bend left=15] node [above] {A} (1up);
\node[] at (0.15, -0.03) (0down) {};
\node[] at (0.65, -0.03) (1down) {};
\path (1down) edge[pil, bend left=15] node [below] {B} (0down);
\end{tikzpicture}
\end{document}
我的问题是 MWE 本身运行良好,但将相同的代码添加到我原来的 tex 文件中会导致上述问题。
更新:终于找到了“MnonWE”:
\documentclass[11pt]{article}
\usepackage{commath}
\usepackage{tikz}
% arrows in tikz
\usetikzlibrary{shapes,arrows,chains,positioning,calc}
\usetikzlibrary{arrows.meta}
\begin{document}
\begin{tikzpicture}[scale=8]
\tikzset{
%Define standard arrow tip
>=stealth',
%Define style for boxes
punkt/.style={
rectangle,
rounded corners,
very thick,
text width=6.5em,
minimum width = 5em,
minimum height=4em,
text centered},
% Define arrow style
pil/.style={
->,
thick,
shorten <=2pt,
shorten >=2pt,}
}
\node [punkt, draw = blue] at (0,0) {$\forall i:x_i>y_i$};
\node [punkt, draw = red] at (0.8, 0) {$\forall i:x_i<y_i$};
%
\node[] at (0.15, 0.03) (0up) {};
\node[] at (0.65, 0.03) (1up) {};
\path (0up) edge[pil, bend left=15] node [above] {A} (1up);
\node[] at (0.15, -0.03) (0down) {};
\node[] at (0.65, -0.03) (1down) {};
\path (1down) edge[pil, bend left=15] node [below] {B} (0down);
\end{tikzpicture}
\end{document}
\usepackage{commath}
因此,仅当包含在前言中并$\forall i:x_i>y_i$
在 \node 中使用时,文件才会编译失败。

我正在测试整洁@hpekristiansen MWE:
\documentclass{article}
\usepackage{commath}
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}
\node {$:$};
\end{tikzpicture}
\end{document}
问题在于此代码片段commath.sty
(大约第 280 行):
% Fix alignment of := in mathmode
\mathchardef\ordinarycolon\mathcode`\:
\mathcode`\:=\string"8000
\begingroup \catcode`\:=\active
\gdef:{\mathrel{\mathop\ordinarycolon}}
\endgroup
这会循环显示节点文本(不确定为什么)。可能应该通知软件包作者,看他们能否修复它。
暂时,您可以将文件复制commath.sty
到当前目录,并删除这些行。
然后它应该可以正常工作,即使你失去了调整:=
(无论如何我都会用另一种方式来做;玩数学代码和猫代码,正如你所见,是危险的。它肯定也会做一些有趣的事情babel
)。
