将章节编译到主文档时出错

Question

对于我的论文，我想将各种 tex 文档编译为章节。不幸的是，当我尝试链接各个章节时，我收到以下错误：

文件：chapter_1/tex/chapter1 "!缺失数字，视为零。}\section{introduction}
文件：chapter_1/tex/chapter1 "!计量单位非法（插入 pt）。}\section{introduction}

以下是我的 LaTex 代码片段：

编译器的主要文件即各个章节：

我正在使用 TeX Maker。我还确保所有软件包都是最新的。

我在网上看到其他帖子说这可能与标题安全包，但无法找到解决方案。

非常感谢您的支持！

该\import命令基于命令，它基本上将指向的文件粘贴到/\input的位置。其中包括和其余的前言。当然，这是行不通的！\input\import\documentclass

相反，你应该使用subfiles包。请参阅如何将现有的 LaTeX 文件作为论文附录的章节？

我不完全确定这是怎么回事，因为我得到了更具描述性的错误Can be used only in preamble。但是，我使用了一个非常干净的最小文档，并且随着配置的增加，事情变得更容易混淆。
