我在序言中说过：
%Number figures, eqns by chapter
\usepackage{chngcntr}
\counterwithin{figure}{chapter}
\counterwithin{equation}{chapter}
但是我的所有方程式......甚至在第 3 或 4 章中，仍然以 0 作为其主要数字：
知道如何修复此问题吗？
我正在使用带有 Tufte 风格书籍模板的 Overleaf：
\documentclass{tufte-book}
\hypersetup{colorlinks}% uncomment this line if you prefer colored hyperlinks (e.g., for onscreen viewing)
%Number figures, eqns by chapter
\usepackage{chngcntr}
\counterwithin{figure}{chapter}
\counterwithin{equation}{chapter}

答案1
tufte-book默认情况下，的 s\chapter不进行编号。原因是文档类将计数器设置secnumdepth为-1（在 495 行中\input{tufte-common.def})。为什么这很重要？章节在章节级别 0 中定义，并且设置secnumdepth为-1，章节会进行编号。此外，章节计数器不会递增。这就是为什么您的章节引用仍为0。
为了解决这个问题，您可以手动增加计数器chapter（在s\refstepcounter{chapter}之后使用，而不是 a ）或通过以下补丁自动增加计数器：\chapter\chapter*
\usepackage{etoolbox}
\makeatletter
\patchcmd{\Hy@org@chapter}% <cmd>
{\ifnum}% <search>
{\refstepcounter{chapter}\ifnum}% <replace>
{}{}% <success><failure>
\makeatother
