tikz节点生成错误

好的，我正在用 tikz 做我的项目，其中有状态和节点。当我想生成我的节点时，它显示错误消息：Package tikz 错误：(、+、坐标、pic 或节点预期。

我的代码：

     \documentclass{article}


    \usepackage{pgf}
    \usepackage{tikz}
    \usetikzlibrary{arrows,automata}
    \usepackage{iftex}
    \ifPDFTeX
       \usepackage[utf8]{inputenc}
       \usepackage[T1]{fontenc}
       \usepackage{lmodern}
    \else
       \ifXeTeX
         \usepackage{xltxtra}
       \else 
         \usepackage{luatextra}
       \fi
       \defaultfontfeatures{Ligatures=TeX}
    \fi
    \usetikzlibrary{positioning}


    \tikzset{
        state/.style={
               rectangle,
               rectangle split,
                rectangle split parts=2,
                 rectangle split part fill={red!30,blue!20},
               rounded corners,
               draw=black, very thick,
               minimum height=4em,
               inner sep=3pt,
               text width=2cm,
               text centered,
               },
    }
    \begin{document}
    \begin{tikzpicture}[->,>=stealth',shorten >=1pt,auto,node distance=4cm,
                        semithick]

      \node[state] (A) {text\\txet \nodepart{two} blue background \\ here};
      \node[state]         (B) [right of =A]{text\\txet \nodepart{two} blue background \\ here};
      \node[state]         (C) [right of=B] {text\\txet \nodepart{two} blue background \\ here};
      \node[state]         (D) [below right of=A] {$q_c$};
      \node[state]         (E) [right of=D]       {$q_e$};
     \node[state]         (F) [right of= E] {$q_f$};

        \path (A) edge                node (C)
              (B) edge                node {OK} (E)
        \end{tikzpicture}

\end{document}

我做错了什么？

答案1

嗯，请注意

错误的是：right of =A
正确的是：right=of A

问题：\node[state] (B) [A 的右侧上方，标签=左侧：$v_2$] {$5$};

没问题 \node (B) [在 A 的右侧上方,标签=左侧:$v_2$] {$5$};

\path 之后必须有 ;。

现在你的代码可以编译了。

下面你的代码进行了调整

  \node  (E) [right= of D]       {$q_e$};
  \node  (F) [right= of E] {$q_f$};
    \path (A) edge                node {} (C)
          (B) edge                node {OK} (E);
    \end{tikzpicture}
