文本文档中的 \path 命令问题

我正在处理 TikZ 图形的问题。我在新文档中完成了图形。现在，我想将其包含在文本中。当我在新文档中编译代码时没有问题，但是..当我将代码复制到文本文档中时，我无法编译它。

问题在于 \path 命令。如果我从代码中删除它们，则不会出现问题，但如果不删除它们，则无法编译文档。

如果有人知道如何解决这个问题，我将不胜感激。

谢谢。

抱歉打扰了。我是这个网站的新用户。

这里是代码：

\documentclass[spanish,a4paper,12pt]{book}

\usepackage[english]{babel}
\usepackage[utf8]{inputenc}
\usepackage{graphicx}
\usepackage{xcolor}
\usepackage{tikz}
\usetikzlibrary{arrows,snakes,backgrounds}
\usetikzlibrary{shapes.geometric}

\begin{document}

\thispagestyle{empty}

\begin{center}


\begin{tikzpicture}

\large

\tikzstyle{block} = [rectangle, draw=blue, thick, fill=blue!20, text centered,minimum     height=3em];

\tikzstyle{line} = [draw, thick, -latex',shorten >=0pt];

\tikzstyle{hex}=[regular polygon, regular polygon sides=6, draw=blue, thick, fill=blue!20, text centered,minimum height=3em];

\matrix [column sep=10mm,row sep=15mm]
{
% row 1
& \node [block,text width=6cm] (update) {Update properties}; \
% row 2
&
\node [block,text width=7cm,minimum height=3em] (momentum) {Solve momentum equations};     \
% row 3
& \node [block,text width=11cm] (pressure) {Solve pressure correction (continuity)    equation.\\ Update pressure face mass flow rate}; \
% row 4
& \node [block,text width=10cm] (energy) {Solve energy, species, turbulence\\ and other   scalar equations}; \
% row 5
& \node [block, text width=5cm,rounded corners] (converge) {Converged?};
& \node [hex](hexx) {Stop}; \\
}; 

\tikzstyle{every path}=[line]
\path (update) -- (momentum);
\path (momentum) -- (pressure);
\path (pressure) -- (energy);
\path (energy)-- (converge);
\path (converge) -- node [above] {Yes}(hexx);
\path (converge.west)-- node [above] {No} ++(-4,0) |- (update.west);


\end{tikzpicture}

问题是西班牙语模块以速记字符的形式babel激活。>

使用csquotes并添加es-noquotes到的选项babel：

\documentclass[a4paper,12pt]{book}
\usepackage[english,spanish,es-noquotes]{babel}

csquotes（如果您确实需要，请参阅嵌套引用的文档）。

否则，关闭环境持续时间的简写：

\documentclass[a4paper,12pt]{book}

\usepackage[english,spanish]{babel}
\usepackage[utf8]{inputenc}
\usepackage{graphicx}
\usepackage{xcolor}
\usepackage{tikz}
\usetikzlibrary{arrows,snakes,backgrounds}
\usetikzlibrary{shapes.geometric}

\begin{document}

\thispagestyle{empty}

\begin{center}
\shorthandoff{>} %%%% <--- turn off the > shorthand
\begin{tikzpicture}
\tikzstyle{block} = [
  rectangle, 
  draw=blue,
  thick,
  fill=blue!20,

  minimum height=3em
];
\tikzstyle{line} = [
  draw,
  thick,
  -latex',
  shorten >=0pt
];
\tikzstyle{hex} = [
  regular polygon,
  regular polygon sides=6,
  draw=blue,
  thick,
  fill=blue!20,
  text centered,minimum height=3em
];

\matrix [column sep=10mm,row sep=15mm] {
