我在运行 latexdiff 时遇到了问题，即使是最简单的使用 tikz-cd 进行交换图的文件。
这是一个简单的例子。我做错了什么？
旧文本
\documentclass{article}
\usepackage{tikz-cd}
\begin{document}
Here is a diagram.
\begin{equation}
\begin{tikzcd}
A \arrow{r} & B
\end{tikzcd}
\end{equation}
\end{document}
new.tex：
\documentclass{article}
\usepackage{tikz-cd}
\begin{document}
Here is no diagram.
\end{document}
命令：
latexdiff old.tex new.tex > diffs.tex ; pdflatex diffs
输出：
This is pdfTeX, Version 3.14159265-2.6-1.40.19 (TeX Live 2019/dev/Debian) (preloaded format=pdflatex)

--add-to-config PICTUREENV=tikzcd 应该使用技巧来告诉 latexdiff 忽略 tikzcd 环境的内容。
