摘要未插入目录

Question

我已经尝试了一段时间，但每次都会出现相同的错误消息。

！LaTeX 错误：出现错误 — — 可能缺少 \item。

我想要实现的只是将摘要作为目录的一部分插入。

Answer 1

您使用的article文档类不使用chapter标题。这就是导致错误的原因。因此，更改\addcontentsline{toc}{chapter}{abstract}为\addcontentsline{toc}{section}{abstract}

此外，如果您想要大写字母 A 的“Abstract”，则使用\addcontentsline{toc}{section}{Abstract}
