我下载了一个 C 模板，并用它来写我的简历。在“工作经验”部分，我决定添加一行粗体字，用于\textbf将经验归类为所获得的相关可转移技能。在rSubsection我的第一份简历（参见项目管理）中，它起作用了。在第二份简历（rSubsection如下所示）（技术技能）中，第一\textbf行出现错误。第二份简历（团队合作）工作正常！
\begin{rSection}{Working Experience}
\begin{rSubsection}{University of city}{November 2021 - Present}{Postdoctoral Researcher}{city, country}
\textbf{Project Management}
\item Leading a research project
\item Delivered project milestones on time.
\end{rSubsection}
\begin{rSubsection}{University of city}{October 2016 - October 2019}{Imaging Scientist}{City, Country}
\textbf{Technical Skills} %the moment I use this line I get an error on the line below
\item Lab Maintenance: microscope setup, restocking of basic consumables.
\textbf{Teamwork}
\item Sharing expertise with undergraduate and postgraduate students
\end{rSubsection}
错误信息：
! LaTeX Error: Something's wrong--perhaps a missing \item.
See the LaTeX manual or LaTeX Companion for explanation.
Type H <return> for immediate help.
...
l.73 \item M
aintenance: microscope setup, restocking of basic consumables.
这也是模板部分：

没有\item缺失，所以我添加的内容肯定存在一些问题\textbf，但我有时不明白它是如何工作的，有时则不然！
答案1
rSectionOP 代码是来自代码由 Steven B. Segletes 提供回答如何禁用 rSubsection 中的列表？。
在链接的代码中，您可以在rSubsection环境中插入文本或表格。不仅仅是\item。
但环境中的第一件事rSubsection需要是一个\item。
您可以使用 隐藏列表项中的项目符号\item[]。
为了防止所有内容都以粗体显示，我\normalfont在环境代码中添加了rSection。
我还删除了OP 代码中未使用的\namesize、\addressskip和的定义。\nameskip
OP 漏掉了\usepackage{ifthen}所以我添加了它（需要\ifthenelse）。
\documentclass[11pt]{article}
\usepackage{ifthen}

笔记：Steven B. Segletes 的代码用于本教程来自 Drshika Asher，以便用 LaTeX 制作简历。这可以给出以下布局：
（与 OP 提供的代码无关，但在 Drshika Asher 的教程中，最后一个代码示例缺失了\item[]。\textbf{Coursework:}此外，在提供的包含完整代码的 Overleaf 项目中，\item[]缺少一些代码：第 100、128、133、142 行）。
