我最近换了电脑，重新安装了 MikTeX 和 TeXmaker。我在之前的电脑上处理一个 revtex 文档，编译起来没问题，但现在编译时出现错误。
我在完整文档中收到错误“！Extra \endgroup。”，因此我尝试在一个最小的工作示例中重现它：
最小工作示例：
\documentclass[aps,prl,10pt]{revtex4-2} \begin{document} hello \end{document}
但是这次，我收到错误“Class revtex4-2 Info: Unrecognized LaTeX tabular. Please update this document class! (Provide with finger crossing.) on input line 2.”
我尝试重新安装 MikTeX，重新安装 revtex，但错误仍然存在。我检查了一下，我使用的是 revtex 4.2f 版本。这些是我在 MikTeX 中安装的软件包：

答案1
已解决。我在父目录中有旧版本的 revtex 文件（4.2f 之前的版本），我认为这是导致编译错误的原因。
