为什么如果我使用\documentclass{book}以下代码作为示例，代码可以工作，而如果我使用，classicthesis就会出错？抱歉篇幅太长，但这就是 MWE。
在示例中\textwidth，应用了 found，don't，因此我认为与边距相关的内容与错误无关。对我来说，问题出在 .aux 文件上。
\documentclass{scrreprt}
\usepackage[%
pdfspacing,%
linedheaders,%

\usepackage{pgf}
\usepackage{xparse}
\usepackage{siunitx}
\usepackage{environ}

答案1
真正的问题是在.aux你输入的文件。你会发现类似这样的命令
\providecommand\hyper@newdestlabel[2]{}
\@writefile{toc}{\vspace {-\cftbeforechapskip }}
\@writefile{lof}{\deactivateaddvspace }
\@writefile{lot}{\deactivateaddvspace }
这意味着该.aux文件需要@是一封信件。
之前向上移动\makeatletter（无论如何你都在使用它）\input{\nameofthisfile.aux}会使错误消失。
顺便说一下，\jobname由系统设置为输入文件的名称。
