本质上，我想在下一张幻灯片中突出显示某些边缘，并使用 TeX.SO 其他地方提供的答案，但问题实际上出在scopeTikZ 的功能中：我收到以下错误
瞄准镜和 Beamer 是否存在不兼容的情况？

如果您在框架中使用易碎内容（例如 tikz 图片），请将fragile选项传递给框架：

我在这里找到了解决方案：https://groups.google.com/forum/#!topic/comp.text.tex/ox8dEYWg494
修复level/.style={sibling distance=60mm/#1需要改为level/.style={sibling distance=60mm/####1
