调整图表代码

Question

以下是我试图在背面编译的代码：

\begin{tikzcd}[row sep=huge]
H_{\bullet}(\Sigma X)
   \arrow[r,"c_*"]
   \arrow[dr,bend right,"\Delta"'] &
H_{\bullet}(\Sigma X\vee\Sigma X)
  \arrow[r,"(f\vee g)_*"]
  \arrow[d,shift right=0.5em,"j?"'] &
H_{\bullet}(Y) \\
& H_{\bullet}(\Sigma X)\oplus H_{\bullet}(\Sigma X)
  \arrow[u,shift right=0.5em,"i_{1*}\oplus i_{2*}"']
  \arrow[ur,bend right,"f_*\oplus g_*"']
\end{tikzcd}

但每次编译时都会出现编译错误，其中一些错误是：

1- 此部分的错误 $ \arrow[r,"c_“]$ 是以下错误：包 pgfkeys 错误：我不知道密钥 '”c_\par ' 我将忽略它。也许你拼错了。

2- 此部分 $ \arrow[dr,bend right,"\Delta"']$ 的错误是以下错误：包 xcolor 错误：未定义颜色“\Delta \T_1 \textquotedblleft'。”

3- 此部分的错误 $\arrow[r,"(f\vee g)*"]$ 是以下错误：包 pgfkeys 错误：我不知道密钥“”（f\vee g）*\par ' 我将忽略它。也许你拼错了。

4- 此部分 $\arrow[d,shift right=0.5em,"j?”']$ 的错误如下：包 xcolor 错误：未定义颜色“j? \T_1 \textquotedblleft'。”

这是我从一开始的文档：

  \arrow[l]
  \arrow[uul,out=100,in=-10,"g_*"'] 
  \arrow[ul,"i_{2*}"']
  \\
  \end{tikzcd}
\]

任何有助于解决这些问题的帮助都将不胜感激！

提前致谢。

您需要添加

\usetikzlibrary{babel}

文档序言因为\usepackage[ngerman]{babel}改变一些符号的含义tikzpicture。通过添加 Ti 进行更正/恢复钾Z 库babel。MWE 的意思是：

\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{lmodern}
% Sprache (neue deutsche Rechtschreibung)
\usepackage[ngerman]{babel}

\usepackage{tikz-cd}
\usetikzlibrary{babel} % <-----

\usepackage[margin= 1 in]{geometry}

%\addtolength{\oddsidemargin}{-.875in}
