我一直在尝试编译一个 beamer 演示文稿，并尝试了所有方法：重新安装 (MikTeX) 和运行 updmap.exe 等...但都无济于事。我一直收到此消息。我将不胜感激任何能为我提供帮助的人。谢谢！！
错误

答案1
这是 miktex 中的打包错误。sansmathaccent 包缺少 tfm 和 vf 文件（https://ctan.org/tex-archive/fonts/sansmathaccent/tfm，https://ctan.org/tex-archive/fonts/sansmathaccent/vf）。
我提交了一个错误报告
https://github.com/MiKTeX/miktex-packaging/issues/162
这个问题应该很快得到解决。
答案2
我遇到了同样的问题 - 搜索后我找到了帖子错误：！字体 OT1/mathkerncmss/m/sl/10.95=mathkerncmssi10 位于 10.95pt 无法加载：未找到公制 (TFM) 文件我认为这是一个相同的问题，并给出了两个解决方案：
- 卸载 sansmathaccent 软件包并在要求安装时单击“否” - 这似乎对某些人有用，但对我来说却不起作用。
- 包括包 newcent - 这使其可以编译，但也会改变不希望的字体。
