beamer我在使用和 时遇到了一个奇怪的问题tikz。以下 MWE 无法编译。\alert从作者行中删除 ，或\usepackage{tikz}或框架中的数学内容就足以解决问题。除此之外，日志文件中的一些错误与字体有关，编译过程似乎涉及许多mktextfm过程。
这个问题可能过于局部化，谷歌中缺乏相关结果迫使我得出这个结论。但是，我相信我不是第一个编译这些软件包的人，我的发行版是最新的，（据我所知）我没有忘记括号或反斜杠。我遗漏了什么？所有这些软件包背后是否有一个简单的原因并解释了这个问题？

您的日志文件显示字体存在问题，但这似乎无关紧要。如果我处理您的 MWE，我会得到

并且实际上 tikz 似乎\next在 scratch 宏中留下了一个稍微危险的定义，而 beamer 显然在不检查它是否完全安全的情况下就使用了它。使其安全可以让示例运行而不会出现错误
