我正在尝试将之前在 Obsidian 中绘制的 tikz-cd 图表插入到我的 TeX 文档中。包含该图表的代码是：
\begin{equation*}
\begin{tikzcd}[scale=3]
\mathcal{A} \otimes \mathcal{A} \otimes \mathcal{A}
\arrow[r, "\nabla \otimes \text{id}"]
\arrow[d, "\text{id} \otimes \nabla"] &
\mathcal{A} \otimes \mathcal{A} \arrow[d, "\nabla"] \\
\mathcal{A} \otimes \mathcal{A} \arrow[r, "\nabla"] &
\mathcal{A}
\end{tikzcd}
\end{equation*}
我收到以下错误：
Argument of \language@active@arg" has an extra }.
<inserted text>
\par
l.100 \end{tikzcd}
I've run across a `}' that doesn't seem to match anything.
For example, `\def\a#1{...}' and `\a}' would produce
this error. If you simply proceed now, the `\par' that
I've just inserted will cause me to report a runaway
argument that might be the root of the problem. But if
your `}' was spurious, just type `2' and it will go away.
Runaway argument?
我的序言：

在谷歌上搜索这个错误时，我遇到了一个回答建议找一些符号的替代品。但是，我不知道如何在 tikz-cd 图中"替换。"
PS 这是我第一次在 TeX 文档中使用 tikz-cd，而不是在 Obsidian 环境中，因此在使用 tikz-cd 时也可能出现错误。
答案1
您想加载 Ti钾Z 库babel。
顺便说一句，times已经过时了，而且当涉及到西里尔字母时，它实际上什么也不做。该包tempora支持 Times 式的西里尔字体；我还加载了newtxmathTimes 式的数学符号。
也是\text{id}错误的，应该是\mathrm{id}。
更改包加载顺序：hyperref应为最后。无需cmap或inputenc。
