Cleveref 没有建立链接：如何链接定理等？

Question

下面的示例可能并不完全是“最小的”，因为我不确定是否存在任何软件包相互依赖关系，我希望您能够准确地看到我在做什么。理想情况下，我希望“Definition 1.0.1”的全部内容都链接到一个无色、无下划线的链接，当您在查看 PDF 时将鼠标放在它上面时，该链接主要可检测到。如果只有数字被链接，那就足够了，但不是那么好。当我提到“Theorem 2.0.1”时，我想要同样的东西。当我使用时，\ref没有链接，切换到\cref只会出现未链接的问号（用绿色箭头表示）。感谢您查看此内容。

\begin{defin}\label{def:DEF1}
    A definition is supposed to tell you what something means.  In this case, a definition is something I will want to link as a cross-referenced item later via the label.
\end{defin}

\section{Second Fake Section}
\begin{thm}\label{thm:THM1}
Even if I cite this with CREF later, there won't be the link I want.
\end{thm}

\begin{proof}
As in Definition \cref{def:DEF1}, this doesn't get linked.
\end{proof}


\section{Third Fake Section}
You can see that links are not happening for either Definition \cref{def:DEF1} or Theorem \cref{thm:THM1}.  For some reason, switching from REF to CREF just makes these question marks appear.

您必须加载ntheorem 前 cleveref。并删除该thref选项。

我对你的代码做了一些更改，例如注释掉textcomp不再需要的代码；我hidelinks只是针对下面的图片进行了注释。
