类 dinbrief 和包 pdfpages 的组合对我来说无法编译。以下是 MWE（好吧，在这种情况下是最小的非工作示例）：
\documentclass[]{dinbrief}
\usepackage[demo]{pdfpages}
\begin{document}
Text here
\includepdf[pages=1]{somePdfFile}
\end{document}

我认为这可以直接追溯到软件包。这是在 Windows 上新安装的 Miktex。我在安装了较旧 Miktex 的旧计算机上使用了完全相同的类和包组合，因此可能在此期间出现了不兼容的情况。您知道如何解决这种不兼容问题吗？
答案1
dinbrief自 2020/10/01 起，它与所有 LaTeX 版本均不兼容。（恕我直言，它之前甚至不完全兼容，但从该 LaTeX 版本开始，它破坏了\begin{document}LaTeX 的代码，因此经常导致错误。）所以你不应该再使用它了。
解决方法对于旧信件，你仍然需要编译，您可以尝试使用包回滚 LaTeX 版本latexrelease：
\RequirePackage[2020/03/02]{latexrelease}
\documentclass[]{dinbrief}
\usepackage[demo]{pdfpages}
\begin{document}
Text here
\includepdf[pages=1]{somePdfFile}
\end{document}
但请注意，这并不适用于所有文档，因为其他一些软件包的当前版本依赖于当前的 LaTeX 版本，因此回滚会失败。在这种情况下，您需要付出额外的努力才能使其再次运行。
对于（不仅仅）德语字母，有几种替代方案可以与最新的 LaTeX 版本配合使用，例如，g-brief，scrlttr2，scrletter，akletterETC。
