我正在尝试编写我的博士论文。它以前（几个月左右）有用，但从那时起，事情发生了变化，因为我得到了一个
undefined control sequence
与以下相关的错误caption包裹。
我已将其全部精简为一个最小示例。不过，我保留了序言中的所有包声明。

正如您所看到的，它实际上写出了一个.pdf看起来不错的文件，但它完全搞乱了我的论文编写。有人对 LaTeX 新手如何解决这个问题有什么建议吗？
答案1
文档类别的检测thesis（http://www.ctan.org/pkg/thesis) 在软件包的早期非常幼稚，caption因为我不知道还会调用其他文档类thesis。这个问题已于 2009/11/15 修复，因此您的caption软件包似乎比这更老，而且您偶然发现了一个 3 年前就已解决的问题。
如果无法更新 TeX 发行版，您可以尝试重命名文档类（例如，重命名为mythesis或其他名称thesis），或者尝试caption使用自己的labelfont=和textfont=设置加载包，例如
\usepackage[hang,small,labelfont=,textfont=]{caption}
这将覆盖对 CTAN文档类的labelfont和支持，从而删除对和（CTAN-文档类的内部命令）的支持。textfontthesis\cph@font\cpb@fontthesis
顺便说一句：该subfigure包不应用于新文档，它仅可用于使旧文档仍可编译。
