`\usetikzlibrary{babel}` 与 `tkz` 宏 `\tkzRep` 和 `\tkzDrawLine` 之间不兼容

在下面的 MWE 中，除非图片 (1) 中\usetikzlibrary{babel}加载了 ，否则会标记编译错误。但是，图片 (2) 和图片 (3) 中的加载都标记编译错误。奇怪的是，所有其他宏似乎都运行良好，例如，等等。有没有办法摆脱这种困境？pic ["$\alpha$",draw, fill=yellow]{angle= A--B--C}!Missing \endcsname inserted\usetikzlibrary{babel}\tkzRep[color=red, ynorm=2]\tkzDrawLine(A,B)!Undefined control sequence.\tkz\tkz\tkzDrawPoints\tkzDrawSegment

答案1

图书馆babel所做的不过是

\tikzset{
  handle active characters in code,
  handle active characters in nodes
}

它的作用是将各种字符的字符代码改回其默认设置。我无法提供确切的细节，但看到错误说

! Undefined control sequence.
l.1 \tkz
        @Rep@ylabel

似乎\tkz@Rep@ylabel在某个地方遇到了宏，而该地方的字符代码@已设置为其他（我猜测），因此无法在宏中使用它。

无论如何，您可以通过本地设置来解决这个问题/tikz/handle active characters in nodes=false

IE

\tkzRep[/tikz/handle active characters in nodes=false,color=red, ynorm=2]

\tkzDrawLine[/tikz/handle active characters in nodes=false](A,B)

代码输出
