以下是一个（相当）简单的例子：
\documentclass{book}
\usepackage{amsmath}
\usepackage{amsthm}
\usepackage{thmtools}
\declaretheoremstyle[
spaceabove=6pt, spacebelow=6pt,
headfont=\normalfont\bfseries,
notefont=\itshape, notebraces={(}{)},
bodyfont=\itshape,
postheadspace=1em
]{mystyle}
\declaretheorem[name=Theorem, parent=section, style=mystyle,
refname={Theorem,Theorems},
Refname={Theorem,Theorems}]{theorem}
\declaretheorem[name=Proposition, sibling=theorem, style=mystyle,
refname={Proposition,Propositions},
Refname={Proposition,Propositions}]{prop}
\usepackage{hyperref}
\hypersetup{%
colorlinks = true,
linkcolor = blue,
urlcolor = magenta,
citecolor = red,
pdfpagemode = UseNone,
pdfpagelayout = SinglePage,
pdfdisplaydoctitle = true,
plainpages = false}
\usepackage[capitalize]{cleveref}
\crefname{prop}{Proposition}{Propositions}
\begin{document}
\begin{prop}\label[prop]{prop:112}
Testing this out!
\end{prop}
\begin{prop}\label[prop]{prop:113}
Still Testing!
\end{prop}
\cref{prop:112} and \cref{prop:113}
\end{document}
问题是两个链接都指向第一个命题。我还得到了错误
destination with the same identifier (name{prop.\\theHprop\040}) has been already used, duplicate ignored。
有人知道我需要采取什么步骤来解决这个问题吗（我以为我已经做得够多了！）。也许这是相关的，但我也得到了错误
Package thmtools warning: Your version of cleveref is too old!
但我刚刚更新了两个包！
答案1
您的示例对我来说很有效。（没有来自 thmtools 的日志文件消息）。软件包版本
