我收到命令、、\tableofcontents和相同的错误：\listoffigures\listoflistings\chapter
Command \textcap unavailable in encoding T1.
即使克隆一个新的乳胶模板也会导致此错误，例如来自 GitHub 的这个：https://github.com/timkpaine/oreilly-latex-template
需要明确的是，PDF做生成，但文档中缺少所有这些内容（标题、目录等）
以下是该示例的序言，仅供参考（抱歉，有点长）：

我在 Mac 上使用 VS Code 和 LaTex Workshop。我觉得我遗漏了一些可能导致此错误的小细节。我已经有一段时间没用过 LaTeX 了，所以如果这很明显的话，请多多包涵！
答案1
问题是将在文档开始时hyperref定义，从而覆盖您的字体定义。\textcap
如果你真的想要将 Helvetica 与 Computer Modern（或其他字体）混合，然后使用适当的方法（不是固定字体）。但解决您的问题的方法是使用\textcap其他字体替换，例如\chapterfont。
顺便说一句，titlesec与 不兼容scrbook。不要重新定义\hline；而是使用booktabs规则。还删除该pdftex选项。
