章节之后的章节与我获得的模板不兼容

Question

我复制了一个模板，用于为我的文档制作一个漂亮的目录。但是在我的章节中添加了一个部分后，其余章节会给出错误：“出现问题 - 可能缺少/项目”。

Answer 1

TeX 错误行号非常准确地指出了错误的来源（一次:-) 它位于\noindent章节 toc 定义的末尾。

如果你注释掉或者删除\noindent文件第 37 行，它看起来会像这样：

                                  {\scshape\small\chaptername~\thechapter}\\\sffamily#1%
                               \protect\end{leftbar}}\par%\noindent
                        }%

然后它运行就不会出错了。
