我是 Latex 新手，正在学习如何使用 Beamer 进行演示。我找到了一个示例，遇到了一个问题，正在寻求帮助。错误消息如下：
LaTeX 警告：标签可能已更改。请重新运行以获取正确的交叉引用。
) !pdfTeX 错误：pdflatex (文件 mathkerncmssi10)：未找到 657 处的字体 mathkerncmssi10 ==> 发生致命错误，未生成输出 PDF 文件！
抱歉，但“MiKTeX 编译器驱动程序”没有成功。
日志文件希望包含让 MiKTeX 再次运行的信息：

答案1
真正的错误信息是这样的
!pdfTeX error: pdflatex (file mathkerncmssi10): Font mathkerncmssi10 at 657 not found ==> Fatal error occurred, no output PDF file produced!
这at XXX表明 pdflatex 正在寻找合适的位图字体（分辨率为 XXX），它应该这样做，因为该字体是 type1 字体。这意味着字体映射文件尚未正确更新。
要更新字体映射文件，请在 miktex 控制台（用户模式）中的任务菜单“刷新字体映射文件”中运行。
